Darros Posted November 30, 2011 Share Posted November 30, 2011 (edited) Holy crap. I've been working on these for a while, and I do NOT get them. Also, I can only prove using one side of the equation, not alter both. These are the problems. and Edited November 30, 2011 by Skasaher Quote Link to comment Share on other sites More sharing options...
Mikethfc Posted November 30, 2011 Share Posted November 30, 2011 The second one you can rearrange the last term to (1/cos^2)/(1/sin^2), which is just tan^2. on the LHS you simplify sin^2 + cos^2 to make 1 so you end up with 1 sec^2 =2+tan^2 or sec^2=1+tan^2 which is what you get if you divide the sin^2 + cos^2=1 by cos^2. ANd I'm about to start the other one so I'll get back to you on it Quote Link to comment Share on other sites More sharing options...

Mikethfc Posted November 30, 2011 Share Posted November 30, 2011 Okay for the first one I noticed you said to only focus on one side so for the LHS: you can factor out cos^2 for the num. and denom Cos^2(1-tan^2)/cos^2(1+tan) which leaves you with 1-tan^2/1+tan By completing the square you can show that 1-tan^2=(1+tan)(1-tan) which leaves you with 1-tan on the LHS Multiply by tan and you get tan*(cot-1) as cot=1/tan multiplying by tan is the same as dividing by cot so you get: cot-1)/cot Quote Link to comment Share on other sites More sharing options...

Lord Raven Posted December 1, 2011 Share Posted December 1, 2011 How often are you right about anything little boy? I had to unignore your post because I knew it would be hilariously off. I'm not sure what gives you the right to be suck a fucking prick, especially since asking for help is better than not doing so and leaving yourself hanging out to dry.Also, the most useful trig identities in general are: (sinx)^2 + (cosx)^2 = 1 (secx)^2 - 1 = (tanx)^2 (cscx)^2 - 1 = (cotx)^2 You can form all the other identities from those. Once you get the hang of those, trig identities with single angles aren't too bad. Quote Link to comment Share on other sites More sharing options...

Original Alear Posted December 1, 2011 Share Posted December 1, 2011 he wasnt talking to crash when he said that But he [Obviam] had Kirby [Crash] quoted in what you quoted when you asked why Obviam had to be such a bleeping prick all the time. So I think he was. Quote Link to comment Share on other sites More sharing options...

Aleph Posted December 1, 2011 Share Posted December 1, 2011 (edited) You say that like I was talking to you. I wasn't. Learn to infer. Actually though he never asked to be told "what gives [me] the right to be suck a fucking prick", so I guess any query was implied if present at all. Still, typically people want to know the answer to something when they complain about not knowing it, so I pre-empted him.
