Respuesta :

secθ = cos^(-1)θ is the same as secθ = 1/cosθ 

Secant is a trigonometric function, reciprocal to the cosine. 

People get confused because they tend to link "cosine" and "cosecant" (which is reciprocal to the sine)

Correct definition for secθ = ( Hypotenuse / Adjacent side) in a right angled triangle , where θ is one of the acute angle.

What are trigonometric ratios?

" Trigonometric ratios are defined as in a right angled triangle with respect to one of the acute angle ratios of the sides of the triangle."

According to the question,

Correct definition of trigonometric ratio secθ

In a right angle triangle, the ratio of the hypotenuse to the adjacent side with respect to the one of the acute angle θ.

secθ =  ( Hypotenuse / Adjacent side)

or secθ = (1 / cosθ)

Hence, correct definition for secθ = ( Hypotenuse / Adjacent side).
