Tangent and SecantDate: 2 Feb 1995 11:31:27 -0500 From: pat casey Subject: <None> Please, I need help with the following problem in pre-calculus math: tan b + cot b = sec b csc b Date: 2 Feb 1995 12:12:34 -0500 From: Dr. Ken Subject: Re: <None> Hello there! In problems like these, when you're trying to prove that an identity is true, it's often easiest to put everything in terms of Sine and Cosine. So your equation becomes Sin b Cos b 1 ----- + ----- = ----------- Cos b Sin b Cos b Sin b Now try to eliminate the denominators by multiplying the equation by some stuff. I hope this gets you somewhere! -Ken "Dr." Math |
