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.
