So I'm doing trig identities in my advanced functions course and for some reason my brain just will not even take hold of a basic grasping as to how they work.. Its quite frustrating. I was wondering if anyone knew of any good 'math' websites that would be able to explain something like this well.
The question I am stuck on right now is
And I think you can turn tan into sec 2 x. However, I can't get much farther then that. This is only the third question on my page and I have been sitting here for an hour or so working through them and I'm not getting anywhere. The book we are using gives like 5 total examples for the whole section
I kind of have a test on Friday on this stuff, so I need to learn it pretty quickly.
help is appreciated!
Thank you Divideby0 and badgerigar for helping me out last time.
Well, I did get tan ēx as one of my answers, but my answer book says that the answer is 1 :/ So i'm unsure where they came up with that.
Yes, this was just a simplifying question.
The thing is, normally math comes relatively easy to me, but I think that trig identities use some sort of deducing that I'm just not attuned to..
I asked for help on here, because I'm on the third question of 5.1, and it goes all the way up to 5.5. So I figured if I'm allready stuck here then I really need some help.
And I can't really ask the answer for every single question on this forum.
Thank you both for your help so far though.
Anyone know of any helpful websites?
