Question

If sin theta=1/2 find values of cos^2 theta+ tan^2 theta

Answer 1

i hope it will help u....

Answer 2

solution!!...

$sin \: theta \: = \frac{1}{2}$

$sin \: theta \: = 30$

cos² theta + sin² theta = cos² 30° + sin² 30°

= (√3/2)² + (1/√3)²

= 3/4 + 1/3

= 13/12

hope!!...it helps uhh...❣️
