Simplify (cos(u))/(sin(u))

Problem

cos(u)/sin(u)

Solution

1. Identify the trigonometric ratio presented in the expression.

2. Apply the definition of the cotangent function, which is defined as the ratio of the cosine of an angle to the sine of that same angle.

3. Substitute the expression with its equivalent trigonometric identity.

Final Answer

cos(u)/sin(u)=cot(u)
