We are working on verifing identities using trigonomic identities and such and of the about 50 or so problems we've had to complete i've been able to push through most except for these:

1.(COTx)(SECx)(SINx)=1

2.TANx + COTx = (SECx)(CSCx)

3.(COSt)(COTt) = 1-SIN^2t / SINt

Any help would be so greatly appreciated!!!
