What are the main indicators of […]

How do you know if an equation has more than one solution?
How do you know if an equation has more than one solution? 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 […]
