I just figured this out on my own. For anyone who is curious: tan(t) = x/a means the opposite and adjacent legs of a right triangle with angle t, are x and a respectively. By the Pythagorean Therom, this implies that the hypotenuse is sqrt(a^2 + x^2). Since sin t = opp/hyp, sin t =...

tan(t) = x/a => sin(t) = x/sqrt( a^2 + x^2) ? Folks, In the solution guide to Kline's calculus book, he gives the following in working a problem: tan(t) = x/a => sin(t) = x/sqrt( a^2 + x^2) Can someone explain why this is the case? Thanks, Tristan

In case the poster or anyone is considering "Calculus Demystified". AVOID this book. It is poorly written, unclear and jumps all over the place. I bought it to brush up on Calc I'd forgotten and was totally lost. I ended up buying Kline which is tremendously better.

As for preparing for your Comp Sci stuff, I highly recommend beginning going through the K&R C book here: https://www.amazon.com/dp/0131103628/?tag=pfamazon01-20 (if you aren't already), doing all the exercises (it takes a lot of time, don't expect to get through the book quickly)...

I am having trouble with the fist problem here as well. The equation F = 32m - 32M sin A (where F is the net force on M) is given in the book. I know also that F=ma, yet this equation only accounts for one mass. I also know I can find a maximum of something by setting its derivative...

Well folks after much consideration, I've decided to take the Academic Option. I'll be taking undergraduate math course at my Alma matter, University of Colorado Denver. If I do well and enjoy it, I may apply to the masters program after I take all the prerequisites. I'll be auditing a calc...

Defender - so it is! I missed that one. Thanks!

FYI - I redid the problem using the product rule and got the same answer as the text. However, why does the identity method not work?

I'm working through Kline's Calculus book, and am at the chapter on Integration on Differentiation of Trig Functions. A question asks to find the derivative of: (I've labeled all equations for easy reference) (1) y = sin x * cos x unlike the solution guide which advocates using the product...

Jordan: Be wary of taking the easy path. If computer science is what fascinates you, stick with it and work through the hard stuff. I was in your situation as a college freshman, and I decided to go with my "easier" option, Business/IS over Computer Science because I got a C- in Calc II, and...

Another Academic Option: Since I have a BA, I'll have to pay Graduate Tuition Rates for the under graduate classes I take to "catch up". Would it be wise to go to a state college (one that does not offer a masters program) and get the undergraduate courses out of the way at extremely cheap...

[Sorry for the long rambling post here] Hey folks, I've lurked on this Forum for some time, and you all sound like smart people so I figured I'd ask some advice. I've been a programmer for years, and what I do is starting to get old. I started programming as a kid, almost entirely self...
