That hits home. Yeah it is. In my case our college course didn't teach us the applications part. But skimming forward in the on-line course I discovered some material on image processing using the Singular Value Decomposition. And that wasn't even taught in my college. I learned the basics of...

Hello I seek some guidance and probably suggestions regarding one/more of my afflictions. I am currently studying for my Bachelors in Computer Science. The problem I have is that I feel I haven't learned enough, so I keep revisiting the basics pretty often. I am currently taking few on-line...

That'd be engineering Design.

I don't know about Question B, but for Q. A got a total of three methods of doing it.:smile: http://www.reddit.com/r/cheatatmathhomework/comments/1iy7dg/trig_problems_giving_a_hard_time/

Yes, it is. But I'll look for the solution and post it here as soon as i get it . :smile: EDIT: the question seems to have been removed from the new edition of the book, mine was an old one.

Found a way for A: sin(θ)-cos(θ)=1 [Squaring] sin^{2}(θ)-2sin(θ)cos(θ)+cos^{2}(θ)=1=sin^{2}(θ)+cos^{2}(θ) sin^{2}(θ)+cos^{2}(θ)=sin^{2}(θ)+2sin(θ)cos(θ)+cos^{2}(θ) 1=(sin(θ)+cos(θ))^{2} [Taking square roots] sin(θ)+cos(θ)=\pm1 For B, the 'to prove' equation is an identity but getting it from...

I was having some free time and decided to do some mathematics from my high school mathematics book.These two problems remained, and I am completely clueless to the solution approach. Homework Statement A. If sin(θ)-cos(θ)=1, prove that sin(θ)+cos(θ)=±1 B. If tan(θ)+sec(θ)=10, prove that...
