Can you give me step by steps on how to work these verifying identities?

I've been havin a problem with trigonometric identities from Pre-Calculus. Here are several Problems:

Make sure each identity are identical.

0=theta
sq=Squared
degr.=degrees
cu.=cubed

1. sec(x+y)=Secxsecycscxcscy
cscxcscy-secxsecy
2. cosx+sinx
secx+cscx=sinxcosx

3.cotx-tanx=2cosxcscx-secxcscx

4. cos(theta)sin (theta)=sin2(theta)
2
5. cos(180degr.-theta)=-cos(theta)

6.sin(360degr.+theta)=sin (theta)

7.sec(theta)+1=tan(theta)
tan(theta) sec(theta)-1

8. 1-cosx=(cscx-cotx)sq.
1+cosx

9.1-csc(sq.)theta=sin(theta)-1
1+csc(theta) sin(theta)

10.tan(cu.)theta-1=sec(sq.)theta+tan(theta)
tan(theta)-1
