Question

if cosec^2 theta ×(1+cos theta)(1_ cos theta)=x . find the valie of x
​

Answer 1

Answer:x=tan^2(0),

Where 0 indicates theta.

Step-by-step explanation:

Given that

Cosec^2(0)×(1+cos0) (1-cos0)=x

Or,Cosec^2(0)×{1-sin^2 (0)}=x

Or, Cosec^2(0)×cos^2(0)=x

Or, [1/{Sin^2(0)]×cos^2(0)=x

Or, cos^2(0)/ sin^2(0)=x

The record, x= tan^2(0)
