Question

Express sin67 +cos75 in terms of trigonometric ratios of angles between 0 to 45 .

Answer 1

$\textbf{Answer :}$

Now, sin67° + cos75°

= sin(90° - 23°) + cos(90° - 25°)

= cos23° + sin25°,

since sin(90° - θ) = cosθ
and cos(90° - θ) = sinθ

which is the required solution.

Answer 2

sin(90 -23) = cos 23
cos (90-15) = sin 15
