Please help, I'm 51 and have no clue how to solve these problems, so if anyone can help it would be greatly appreciated.
sinx + tanx/1+cosx=tanx
csc^2-cos^2 xcsc^2=1
cscx=cotx +tanx/secx
secx-tanx=1-sinx/cosx
1/sin^2x + 1/cos^2=csc^2 xsec^2x

What is Verification of Trig Identities ?
According to my understanding
If u don't remember the formula , check out the formula section on this forum.

I have had trouble solving this problem.
Beginning with the trigonmetic identity
cos^2(phi)+ sin^2(phi) = 1
show that the trigonmetric identity
cot(phi) + csc(phi) = sin(phi)/ 1 - cos(phi) holds
any help would be much appreciated.
