If theta is the fundamental period of t...

If `theta` is the fundamental period of the function `f(x) = sin^99 x+sin^99(x+(2pi)/3)+sin^99(x+(4pi)/3)` , then the complex number `z=|z|(cos theta+i sintheta)` lies in the quadrant number.

Text Solution

Verified by Experts

The correct Answer is:
3
Clearly, fundamental period is `(4pi)/(3)`. Then z lies in the third quadrant.
