Question

fine sin square 29+sin square 61

Answer 1

Answer :

We should know a few trigonometric identity rules before solving the problem l.

Here, sin (90 - θ) = cosθ

cos (90 - θ) = sinθ

Now, sin²29 + sin²61

= (sin29)² + sin²61

= {sin (90 - 61)}² + sin²61

= (cos61)² + sin²61

= cos²61 + sin²61

= 1,

since sin²θ + cos²θ = 1

Answer 2

Step-by-step explanation:

sin^2 29+sin^261

sin^29+1/sin^29

answer =1
