Best ResponseYou've already chosen the best response.0Ok. 0 squared is zero and 1 squared is 1. So where the sine function is 0 and 1 would satisfy the equation. Where is sine 0 and where is sine 1?

Best ResponseYou've already chosen the best response.0Basically what I'm saying is that the sine function allows you to get 0 and 1 because the sine function varies from 1 to 1. Since you have to have the function itself equal it's square, you have to obtain 0 and 1 to solve your equation.

Best ResponseYou've already chosen the best response.0pi would work though for sinx=0

Best ResponseYou've already chosen the best response.0Yes, but (3/2)pi would not. That would give you a negative 1, which doesn't satisfy the equation.

Best ResponseYou've already chosen the best response.0sine of pi is 1. so yes it would work. but 3pi/2 would not since it gives you negative 1 for sin(x), where as sin(3pi/2) squared would be 1 since 1 squared is 1

Best ResponseYou've already chosen the best response.0so my final answer would be 0pi+2kpi, pi+2kpi, and (pi/2)+2kpi?

Best ResponseYou've already chosen the best response.0That's right, but the first two can be combined to one. The last one is correct.

Best ResponseYou've already chosen the best response.0Yes. :) Technically you don't need the 0pi, but it doesn't hurt.
