Solve cot theta = sin 2 theta by subst...

Solve ` cot theta = sin 2 theta ` by substituting ` sin 2 theta =( 2 tan theta )/( 1+tan^(2) theta )` and again by substituting ` sin 2 theta = 2 sin theta * cos theta ` and check whether the two answer are same or not .

Text Solution

Verified by Experts

The correct Answer is:
`theta = (2n+1)(pi)/(2)` or `theta = n pi +- (pi)/(4)`
