Simplify cos(-t)sec(t)

Problem

cos(−t)*sec(t)

Solution

1. Apply the even-odd identity for the cosine function, which states that cos(−t)=cos(t)

2. Substitute the reciprocal identity for the secant function, where sec(t)=1/cos(t)

3. Multiply the expressions together to simplify the product.

4. Cancel the common factor of cos(t) from the numerator and the denominator.

Final Answer

cos(−t)*sec(t)=1
