Hello, I coldnt solve this problem

May you help me?

If y=sin(x)*cos(x) then what is the period?

I know Sin(x) and Cos(x) periods 2pi

Tan(x) and Cot(x) are pi but i dont know how i can solve?

Thanks

So,

As I learned answer is pi

1\2*sin(2x) is equal to the pi? How i can show?

Thank you for your attentions. - November 11th 2012, 11:09 AMskeeterRe: Trigonometric problem
