Question

What is a Cotangent?

Answer 1

Trigonometric ratio cotangent:

• Trigonometric ratios are the relationship between the sides and angles of a right-angled triangle.
• A cotangent is the ratio of the adjacent side to the opposite side.

$\mathbf{cot}\mathbf{}\mathbf{\theta }\mathbf{=}\frac{\mathbf{Adjacent}\mathbf{}\mathbf{side}}{\mathbf{Opposite}\mathbf{}\mathbf{side}}$

• It can also be defined as the reciprocal of the tangent value of the angle.

$\mathbf{cot\theta }\mathbf{=}\frac{\mathbf{1}}{\mathbf{tan\theta }}$

Hence,cotangent is trigonometric ratio which is equal to $\frac{\mathbf{1}}{\mathbf{tan\theta }}$
