Question

Cot A .Tan A is equal to

Answer 1

Given: cotA.tanA

To find: The solution to the above statement

Solution: In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. It means that the relationship between the angles and sides of a triangle are given by these trigonometric functions.

Trigonometric functions are also known as circular functions. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant.

In a right-angled triangle,

tanA = sinA/cosA

        = (perpendicular/hypotenuse)/(base/hypotenuse)

        = perpendicular/base

cot A = 1/tanA

         = cosA/sinA

As such, cotA.tanA = 1.
