(-sinAcscA) - (sin^2A + cos^2A) - (tanAcotA)
Evaluate the terms within the parenthesis.
would equal...
is it 3cos^2A - 1 or -2 + 2sin^2A
I have another trig identity question:
cos^2A / (1+ sinA) =
cos^2 A = 1- sin^2 A ....Factorize this using "difference of squares" formula - then eliminate common factor from the numerator and the denominator.
cos^2A + cotAcosA is this right?
