# Thread: help finding the mistake if any

1. ## help finding the mistake if any

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)

It helps if I can see it written in maths form, so I'll write it then have a go...

1. $\csc^2(2x)\sin(x)\tan(x)+2\csc(x)\cos(x)=\sec(x)\c sc^2(2x)$

2. $\frac{\sin(\theta)+\cos(\theta)}{\sin(\theta)}-\cos(\theta)-\frac{\sin(\theta)}{\cos(\theta)}=\sec(\theta)\csc (\theta)$
