Question

I need help!!!!

Answer 1

tan (-theta ) = - tan theta

Answer 2

That doesn't help unless you can explain.

Answer 3

@Gator153760 can you explain this to me if you know how?

Answer 4

you need explanation for tan (-theta) = - tan (theta) ??

did you know sin (-theta) = sin theta ?

Answer 5

i mean sin (-theta) = -sin theta ***

Answer 6

no I don't know any of this. im confused on it and dont know it.

Answer 7

im just going to skip it.

Answer 8

let me show you fw steps, see whether u get those

theta = t

sin t +tan (-t) = 0

sin t - tan t = 0
sin t - sin t / cos t = 0

sin t (1-1/cos t ) = 0

sin t = 0 or 1-1/cost = 0
