My math book shows how to do questions like this by working both sides until they're equal, but my math teacher wants us to work the left side until it is equal to the right.
I can do most of them. I've just got myself stuck on this one.
tanxsin^(2)x + tanxcos^(2)x = tanx
So we're supposed to take the right side and manipulate it using 8 basic identities to make it equal to tanx. I tried changing tanx to sinx/cosx, but that didn't seem to work. Help?
**Edit.. I meant left to right. Oops.
