Question

Simplify sin θ csc θ − sin2 θ.

Answer 1

Remember that csc(x) = 1/sin(x).

Answer 2

so that would drop out?

Answer 3

sin(x) csc(x)-sin(2x)
sin(x)(1/sin(x))-sin(2x)
(sin(x)/sin(x))-sin(2x)
1-sin(2x)

Answer 4

thanks

Answer 5

You understand what I did?

Answer 6

I converted csc(x) to the equivalent (1/sin(x)) so I had sin(x) times 1/sin(x)... which is sin(x)/sin(x) which is the same as 1.

Answer 7

yes i did. i had to look at it a few times but i got it,
