sin(A-B)=(sinA)(cosB)-(cosA)(sinB)
using this formula I get sin(A-B) = - * - cos *
If and , find the exact value of .
My first time using latex! Hopefully it makes my problem easier to read.
EDIT:
so the formula is sin(A-B)=(sinA)(cosB)-(cosA)(sinB)
I guess I should mention I know how to get every value except
and I don't understand why they are telling me
