Simplify cot(x)sec(x)sin(x)

Problem

cot(x)*sec(x)*sin(x)

Solution

1. Rewrite the cotangent function in terms of sine and cosine using the quotient identity cot(x)=cos(x)/sin(x)

2. Rewrite the secant function in terms of cosine using the reciprocal identity sec(x)=1/cos(x)

3. Substitute these identities into the original expression.

cos(x)/sin(x)⋅1/cos(x)⋅sin(x)

4. Cancel the common factors of cos(x) in the numerator and denominator.

1/sin(x)⋅sin(x)

5. Cancel the common factors of sin(x) to simplify the expression to a constant.

Final Answer

cot(x)*sec(x)*sin(x)=1
