What is an example of a complex problem?
Examples include climate change, world poverty, the global financial crisis, child abuse, terrorism and drug abuse. Each of these examples of complex problems impact directly on individuals, families and communities and have implications for the lives of real people.
What are complex problems?
Complex problems are typically defined as those that include the ability to approach them from multiple, sometimes competing, perspectives and which may have multiple possible solutions.
What is complex problem solving?
Complex problem solving is a collection of self-regulated psychological processes and activities necessary in dynamic environments to achieve ill-defined goals that cannot be reached by routine actions. Complex problems usually involve knowledge-rich requirements and collaboration among different persons.

What is a problem with no solution?
No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true.
What is an example of no solution?
When a problem has no solution you’ll end up with a statement that’s false. For example: 0=1 This is false because we know zero can’t equal one. So, we say this problem has no solution. This means no matter what number you put in for the variable x, you will never get anything that equals one another.
What is the formula of no solution?
The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation. If you substitute these values into the original equation, you’ll see that they do not satisfy the equation.
How do you tell if an equation has no solution?
The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur. Use distributive property on the right side first.
How do you know if an equation has two Solution?
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it’s less than 0, there are no solutions. If it’s equal to 0, there is one solution.
How do you know if an equation has infinitely many solutions?
The equation simplifies to the point that it no longer contains a variable, but expresses a true equation, e.g. 0=0 . For example: 2x+2=2(x+1) simplifies in this way. The equation has an identifiable solution and is periodic in nature. For example: tan2x+tanx−5=0 has infinitely many solutions since tanx has period π .
Is 0 0 infinite or no solution?
For an answer to have an infinite solution, the two equations when you solve will equal 0=0 . Here is a problem that has an infinite number of solutions. If you solve this your answer would be 0=0 this means the problem has an infinite number of solutions.
How do you know if there is no solution or infinite solutions?
If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.
What does infinite solutions look like?
An infinite solution has both sides equal. For example, 6x + 2y – 8 = 12x +4y – 16. If you simplify the equation using an infinite solutions formula or method, you’ll get both sides equal, hence, it is an infinite solution.
What is the value of 0 by 0?
0/0 is undefined. If substituting a value into an expression gives 0/0, there is a chance that the expression has an actual finite value, but it is undefined by this method. We use limits (calculus) to determine this finite value.
How do you prove zero factorial is 1?
Simple “Proof” Why Zero Factorial is Equal to One What it means is that you first start writing the whole number n then count down until you reach the whole number 1. For the equation to be true, we must force the value of zero factorial to equal 1, and no other.
Is 0 divided by 0 defined?
In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 00 is also undefined; when it is the form of a limit, it is an indeterminate form.
Is 0 True or false?
The number 0 is considered to be false and all other numbers are considered to be true…. 1 is considered to be true because it is non-zero. The fourth expression assigns a value of 0 to i. 0 is considered to be false.
Is 1 True or false Python?
The Python Boolean type is one of Python’s built-in data types. It’s used to represent the truth value of an expression. For example, the expression 1 <= 2 is True , while the expression 0 == 1 is False .
Is 0 True or false SQL?
SQL – Boolean Data Boolean values are true/false types of data. A Boolean table column will contain either string values of “True” and “False” or the numeric equivalent representation, with 0 being false and 1 being true.
Is 1 True or false Java?
A 0 (zero) is treated as false. In c and C++ there is no data type called BOOLEAN Thats why it uses 1 and 0 as true false value. and in JAVA 1 and 0 are count as an INTEGER type so it produces error in java. And java have its own boolean values true and false with boolean data type.
Why is 1 true and 0 false?
Zero is used to represent false, and One is used to represent true. For interpretation, Zero is interpreted as false and anything non-zero is interpreted as true. To make life easier, C Programmers typically define the terms “true” and “false” to have values 1 and 0 respectively.
What does == mean in Java?
equality operator
What does || mean in Java?
It is a logical operator used in java.It is usually known as OR operator. for example ` if(a==1 || b==1) System. out. println(“Something”);
What is the difference between && and &?
& is a bitwise operator and compares each operand bitwise. It is a binary AND Operator and copies a bit to the result if it exists in both operands. Whereas && is a logical AND operator and operates on boolean operands. If both the operands are true, then the condition becomes true otherwise it is false.
What does != Mean in code?
Equality operators: == and != The equality operators, equal to ( == ) and not equal to ( != The equal-to operator ( == ) returns true if both operands have the same value; otherwise, it returns false . The not-equal-to operator ( != ) returns true if the operands don’t have the same value; otherwise, it returns false .
What does 3 dots mean in Java?
var args
What is String [] args?
The String[] args parameter is an array of Strings passed as parameters when you are running your application through command line in the OS. String[] args means an array of sequence of characters (Strings) that are passed to the “main” function. This happens when a program is executed.
What is difference between == equals () and compareTo () method?
The 2 main differences are that: equals will take any Object as a parameter, but compareTo will only take Strings. equals only tells you whether they’re equal or not, but compareTo gives information on how the Strings compare lexicographically.
Can Varargs be null?
A varargs parameter always has a type, and you can send a single value of that type – or an array of that type. The parameter can be null, although Eclipse wants you cast the null – and your code must be prepared to deal with nulls (or you will throw a NullPointerException ).
