theta=(T) degrees=(D)
1)prove:tan(T)-cot(T)/tan(T)+cot(T)=2sin^2(T) - 1
2)prove:1-cos(T)/sin(T)=sin(T)/1+cos(T)
3)prove:1-tan^2(T)/1+tan^2(T)=1 - 2sin^2(T)

If you've just started this work it's natural that you'll experience initial difficulty. Having someone do the work for you is not the way to overcome this difficulty.
It's better that you invest some time and effort in trying to do them yourself. Then post the work you've done and state where you get stuck.
The help you get will then be much more beneficial.
the 1st one i know i have to change the tan and cot to cos over sines i think but then im still tuck after that.
the second one maybe i change the cos over sin to cot or im still not sure on that 1st step.
the third one seems to be something with the pythagerous ID but then im still stuck.
