using the fundamental identities. Man, this stuff is easy yet for some reason my head doesn't understand it at all..
So I have to convert sec, into sin which I thought was simple but I must be over thinking once again.
(One of the fundamental identities.)
(Changing from tangent to sin/cos)
Now here I get a little lost cause I dunno what to do with that cos. I tried doing something like..
(Multiplied 1 by the common denominator)
Dunno where exactly I went wrong or even if I did it correctly in the first place. Meh, any help on this easy problem would put my mind to ease and help me understand how to do the rest. I just want to learn how to do it correctly ><.
I forgot to add that the answer is secx = 1 / √(1 - sin^2). Also, is there a way to change from cos to sin? o-o
