Answer 1

cot teta is the answer

Answer 2

Step-by-step explanation:

Trigonometric ratios of 90 degree minus theta is one of the branches of ASTC formula in trigonometry.

Trigonometric-ratios of 90 degree minus theta are given below.

sin (90° - θ) = cos θ

cos (90° - θ) = sin θ

tan (90° - θ) = cot θ

csc (90° - θ) = sec θ

sec (90° - θ) = csc θ

cot (90° - θ) = tan θ

Let us see, how the trigonometric ratios of 90 degree minus theta are determined.

To know that, first we have to understand ASTC formula.
