let me know if you still don't know where to go after that

I'm pretty confused

on how to factor?

do you know hot to factor the expression ax+x?

how* (not hot)

no

yes

can you factor that out using what you know about multiplication and division like i did above?

also this way i'm asking you to approach it is not the only approach to take

yes

cos^2?

right
so what does that leave us with?

sin^2(theta)+cos^2(theta)

And that equals?

you need to recall some trig identities for these trigonometric proofs

This one of the most basic ones
It actually has a name

okay si... 1?

I will give you a hint:
Pythagorean Identity

yep

*so

okay i get it now thanks soooo much

You don't have to do both ways. Just one way.

I used a Pythagorean identity in both ways.

way 1 was the way I was trying to get you to go about it the first time around
