sin(x+y)+sin(x-y)=2sinxcosy

y=-log(3)x+2. Find domain, x-intercept and vertical asymptote, I also have to sketch a graph

what is the multi-rule definition for the abs (X^2-2x-8)? I know that x=4 and x=-2 I don't know how to come up with multi-rule

use either the binomial theorm or pascal's triangle

2(x-5)^2=17 How do I solve this using extraction of square roots? HELP!!

The worksheet deals withb trigonometric identities and we have to prove each of them. I'm stumped on this one. Please, if you could help, I'd highly appreciate it!
