IF theta is positive acute angle and tan^2 theta + cot ^2 theta = 82/9 , find the value of tan theta + cot theta?

Question

 2) IF sin theta + cosec theta = 2 , then the value of sin^2 theta + cosec^2 theta

Answer 1

 1)   If θ  is positive acute angle.

Substitute the value 

So  θ  is positive acute angle.

2)
