I need to find the mistake if there is any and I am getting lost please help.

1. csc^2(2x)sin(x)tan(x)+2csc(x)cos(x)=sec(x)csc^2(2x )

2. I need to prove if this is true or false and I am on a time crunch as usual. So if anyone can help me I would appreciate it.

Sin(theta) + cos(theta)/ sin (theta) - cos(theta)- Sin(theta)/cos(theta) = sec(theta)csc(theta)

thanks for any help you can give me Erin
