Answer 2

To solve the expression, you need to know the value of variable "b." However, if you meant to simplify the expression, we can do that without knowing the exact value of "b."

The given expression is:

cos^2(b) + sin^4(b) + sin^2(b)

To simplify, we'll use trigonometric identities:

1. Pythagorean identity: sin^2(b) + cos^2(b) = 1

Using this identity, we can rewrite the expression as:

cos^2(b) + sin^2(b) + sin^4(b)

Now, the expression becomes:

1 + sin^4(b)

That's the simplified form of the expression. If you have the value of "b," you can substitute it in to find the final numerical result.
