Answer:

i need points

Step-by-step explanation:

i need points
Okay, so, start by rearranging the problem (because it’s multiplication, you can do that), you get

(sin^2(x)-cos^2(x))*cos(x)*sec(x) + cos^2(x)

cos and sec are inverses, so they cancel each other out leaving you with

sin^2(x)-cos^2(x)+cos^2(x)

The cos^2(x) cancel each other out leaving you with

sin^2(x)
