Question

can someone help me with this problem "Im dealing with Trig identities, inverse functions, and equations>

Multiply and Simplify
(sin x +csc x) (sin^2 x +CSC^2 x - 1)

Answer 1

I know the answer is \[\sin ^{3}x + \csc ^{3}x\]

Answer 2

but how do they arrive at this answer?

Answer 3

U havent learnred about miltiplying trig functions?

Answer 4

do i just multipy by each term?

Answer 5

before you begin, turn \(\csc^2(x)-1\) into \(\cot^2(x)\)

Answer 6

what im more confused about is what happens to the -1

Answer 7

oh yes, ok i see that identity
