Homework Statement I think this may be a simple problem, but I really have no idea if I did it right because it seemed to easy. Here's the question, consider the Harr Wavelet \psi^{}_n{}_,{}_k{}(x) = 2^n{}^/{}^2{}*\psi(2^n{}x-k) where \psi is the mother wavelet. Prove that...

LCKurtz there's no easy way to put this, but you are THE MAN. Thank you so much, here's the solution I came to thanks to your hints. I really should've came to it easier, but what can you do. |<x1,y1> - <x2,y2>| ≤ ||x1 - x2||*||y1|| + ||x2||*||y1-y2|| Using the first hint so graciously given...

Thank you, but I still don't see how that's applicable, everything's inside an absolute value or a square root so I'm not sure how to get in there? Can I have a double hint?

Homework Statement First I'd like to state the meaning of my notations x = (x0,x1,x2...xn) y = (y0,y1,y2...yn) |x| = absolute value of x ||x|| = Normal of x <x,y> = Inner Product of x and y I have to prove the following |<x1,y1> - <x2,y2>| ≤ ||x1 - x2||*||y1|| +...

Wow, I had no idea about that rule, looks like I shouldn't have passed trig. :/ Haha, thanks everyone who helped me figure this out, very much appreciated. Going to post my final solution because I hate when I find a topic and there's no final sum up of everything to help it all make sense...

OK, I mean absolutely no disrespect if this is a stupid question but I have to know what I am not understanding about this statement. You say they will produce the same value for that x. Are you saying that "-2*sin(π * 1.216) = (1/π)*arcsin(-1.216/2)"? This is when x = 1.216, and they do...

I didn't give up, I tried, 1.1, 1.2, and a couple other starting points, but the only one that wielded a solution was when I typed in 1.1216... which was close enough to the solution that it didn't even have to start the algorithm. The reason it won't work for the function on that interval is...

I need to use Banach fixed point algorithm to solve the equation I listed. I was just wondering if there was some other way to create an "x = f(x)" function with the equation. For example if I use x = -2sinπx, and attempt to solve for the fixed point by starting at 1, we see that it...

Homework Statement OK, I need to solve for the fixed point of the equation 2sinπx + x = 0 on the interval [1, 2]. I know the answer to be ~1.21... but I need to prove it. The Attempt at a Solution I really just need help solving for a proper equation of x. I tried x = -2sinπx...

Oh jeeze, I guess that would give me the ~100000 Pascals I need for the answer, thanks!

Homework Statement Water is coming out of a water cannon at 25m/s, what is the pressure inside the cannon? Homework Equations Bernoulli's (modifiedd): v = √(2gh) -> h = v^2/2g Prssure(liquid) : P = ρgh The Attempt at a Solution...

Ok Physics bros... I think I had a stroke of genius, thanks to Simon Bridge, but I'm wondering of the mathematical/physical legality of what I've done. So... (2000kg)*(9.8m/s^2) = -kx = (2000kg)*(g) = -kx (2000kg + Xkg) * (9.8m/s^2) = -k(x-.1m)= (2000kg +Xkg) * (g) Is it legal to do...

Homework Statement A car has a total mass of 2000kg, and a ground clearance of 40cm. But some fat dude got in and he made the ground clearance 30cm. What is the spring constant for this bad boy of a car? (The dude was so fat he made the shocks act like springs if you can believe it.) Also...
