Simplify the trigonometric expression

D

Step-by-step explanation:

The common multiple is (1 + sin(theta)) * (1 - sin(theta) )

Left fraction

Multiply top and bottom of the fraction by 1 - sin(theta)

Right Fraction

By the same method the right fraction gives.

Combine Left and Right Fractions.

The actual answer out of those given is 2*sec^2(theta) which is D

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
