Question

Prove cotx/secx-tanx -cosx/secxtanx =sinx+cscx

Answer 1

eww trig again >_>

Answer 2

go get a textbook and read it X[)

Answer 3

let c=cosx and s=sinx

LHS=
(s+c)(tanx+cotx)
=(s+c)(s/c+c/s)
=(s+c)((s^2+c^2)/sc)
=(s+c)(1/sc), (s^2+c^2=1)
=(s+c)/sc
=1/c+1/s
=secx +cosecx
=RHS

as required

Answer 4

Thank you :)
