Solving this DE (trigonometry)the problem: Bang postponed. Not big enough. Reboot. #2 20060505 02:26:54
Re: Solving this DE (trigonometry)http://www.mathsisfun.com/forum/viewtop … 635#p32635 This ugly equation comes out to be: "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #3 20060505 06:37:16
Re: Solving this DE (trigonometry)I've learned to not use formulas straight off like that, I learn nothing from it. Kinda ugly, yeah. But thanks anyway for showing that formula, might get in handy, though I preferably do everything from scratch. Bang postponed. Not big enough. Reboot. #4 20060505 09:24:05
Re: Solving this DE (trigonometry)Since the equation is not seperable and not homogenous, I don't believe there is any other way to solve it. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #6 20060505 13:47:16
Re: Solving this DE (trigonometry)I've written the proof or the derivation in post 3, following Ricky's fomula, so you can check my procedure and simply duplicate it before showing the formula. And that will make your solution complete. Last edited by George,Y (20060505 13:52:44) X'(yXβ)=0 #7 20060505 22:45:07
Re: Solving this DE (trigonometry)It's solved now. Thanks George, even though it's not what I was looking for... again. Bang postponed. Not big enough. Reboot. #8 20060506 12:02:40
Re: Solving this DE (trigonometry)Hey, I know how to solve it now, too! Your question is so inspiring! I used to think this kinda trig and derivative mix is my lasttosolve. Last edited by George,Y (20060506 12:04:53) X'(yXβ)=0
