Simplify sec(x)tan(x)

Problem

sec(x)*tan(x)

Solution

1. Identify the trigonometric identities for the given functions in terms of sine and cosine.

2. Substitute the identity sec(x)=1/cos(x) into the expression.

3. Substitute the identity tan(x)=sin(x)/cos(x) into the expression.

4. Multiply the two fractions together by multiplying the numerators and the denominators.

5. Simplify the resulting expression into a single fraction.

Final Answer

sec(x)*tan(x)=sin(x)/cos2(x)
