# tan(pie/2-x) cot x / csc^2(-x)-1

use the fundamental identities to simplify the expression

# tan^2x - tanx/ tan^2x + tanx = tan2x - sec 2x

Hi plz could u help me with this Q. How can prove RHS=LHS

# Double angle identities help

5 Sin 2x - 6 sin x = 0   Sin 2x = cos x   Cos 2x + 5 = 4 sin x

# verify the identity (cosx-cscx)(cosx+1)=-sinx

i need this for my test tomorrow and my teacher isnt asnwering my emails

# Verify the identity 1/tan(theta)csc(theta) = cos(theta)

This is for my trig class, and the directions say to verify the identity. Thanks so much.
