Simplify (cos(A))/(sin(A))

Problem

cos(A)/sin(A)

Solution

1. Identify the trigonometric ratio. The expression consists of the cosine of an angle divided by the sine of the same angle.

2. Apply the identity for the cotangent function. By definition, the ratio of cosine to sine is the cotangent.

3. Substitute the identity into the expression to reach the simplest form.

Final Answer

cos(A)/sin(A)=cot(A)
