I understand that... but how would it cancel out
(1+cos y)/(1+1/cos y)
I understand the 1's would/could cancel, but then you still have:
cos y/(1/cos y)
And the only way I can imagine you would get rid of the denom is multiply the cos y uptop.
I'm clearly doing something wrong, and this is the only problem i've had any issues with thus far.
