Question

y=2sin(x). What is Range and zero?

Answer 1

range is [-2,2]...not sure what you mean by "zero"? The function is zero when \[x=\pm n \pi\] where is an integer.

Answer 2

Thank you. Find zeros means equal 0. like 2sin(x)=0. How to solve that?

Answer 3

well, all you need to solve this is knowledge of the unit circle.\[\sin x=0\]when is sinx =0? when x=0, +-pi, +-2pi, etc...
