Can anyone help me verify these two trigonometric identities

(sinA+cosA)^2= 2+ secAcscA

___________

secAcscA

2/(secAcscA)+ (secAcscA/secAcscA)

2/(secAcscA)+1

2(1/sec+1/csc)+1

2cosAsinA+1

Unfortunately I am stuck and do not know how to proceed(Worried)

For my second problem

sinx+cosx= (cosx/1-tanx)+(sinx/1-cot)

(cosx/(1-sin/cos)+(sinx/(1-cosx/sinx)

I am unsure how to proceed

Can anyone please assist me.
