Answer 2

The expression you provided is: cos(a) + sin^2(a) + cos^2(a) - cos^2(a). Let's break it down step by step.

Simplifying the expression:

1. The trigonometric identity sin^2(a) + cos^2(a) = 1 states that the sum of the squares of the sine and cosine of an angle is always equal to 1. 2. Using this identity, we can simplify the expression as follows: cos(a) + sin^2(a) + cos^2(a) - cos^2(a) = cos(a) + 1 - cos^2(a) - cos^2(a) = cos(a) + 1 - 2cos^2(a)

Further simplification:

To simplify the expression further, we need additional information about the value of 'a'. Trigonometric functions like cosine and sine depend on the value of the angle 'a'. Without knowing the specific value of 'a', we cannot simplify the expression any further.

If you provide the value of 'a', I can help you simplify the expression and calculate the result.
