How do you prove that sin 0 is 0?
Answer) Basically, sin(x) can be defined as (opposite side of a triangle/ adjacent side of a triangle). If the value of the angle between the hypotenuse and the adjacent side is equal to zero, then there is no opposite side, which means the length of the opposite is zero. Hence, the ratio is equal to zero.
What is the value of Cosec 120 degree?
-½
How do you find the value of sin 120?
By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2.
What is the exact value of sec 120 degrees?
-2

How do you find the secant of 30 degrees?
The exact value of sec(30°) sec ( 30 ° ) is 2√3 . Multiply 2√3 by √3√3 .
Why is COT 90 defined?
cot 90 which is the reciprocal of tan90,is nothing but 0. 1/0 cannot be considered as infinite as you cannot take out something from nothing.
