Answer 2

It seems like you want to simplify the expression 1 - (cos(2a) - sin(2a)). Let's break it down step by step:

1 - (cos(2a) - sin(2a))

First, distribute the negative sign inside the parentheses:

1 - cos(2a) + sin(2a)

Now, you can combine the constant terms (1) and (-cos(2a)):

1 - cos(2a)

So, the simplified expression is:

1 - cos(2a)
