Question

cos A into tan A is equal to sin A prove that​

Answer 1

Answer:

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . ... The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

Answer 2

Answer:

cosA × tanA = cosA × (sinA/cosA)

because, tanA = sinA/cosA

so,

cosA × (sinA/cosA) = sinA

Hence the proved
