hmm i don't know that rule..
. This is a standard identity.
I don't know "sec", can you tell me...
Actually I've thought of an easier way... You have .
it doesn't say anything about this in my book and we didn't go over this in class. strange.
.
oh, thank you
Dear somanyquestions, ; By simplification you would get, or Dear Prove It, Your answer is a particular solution. For example also satisfies the given trignometric equation. Hope this helps.
