Yea I know how to use least squares. I just wanted some more insight on what he could possibly be asking. Right now in maple I am taking families of different functions, plotting all the points (for a certain range) of each function in the family. Then I found the best fit curve or line of...

Hi everybody. I am in this computer software class and I have a quiz coming up. My professor gave us a list of what to expect on the quiz and this question came up: Given a family of functions f1, f2, f3, .., fn and given a function f, find the best approximation of f by the family...

Thanks. I actually just found that reading through my old calculus textbook on parametric equations, arc length, and speed. Its been a while since I took calculus and was never the best at speed, velocity and acceleration, etc. My math background has more to do with Actuarial Science and...

Homework Statement First off, I am not a physics student. I am a math major taking a maple software course and there is a question that I can not figure out. The question gives me a radial coordinates r r:= \frac{a*t^{2}*e^{-b*t}}{1+t^{2}} And angular coordinates: θ:=b+c*t^{2/3} Where...

I put it in my calculator wrong. I included the power of 11 in the e, so I had ln(e^{11})= 11. It should be (ln(e))^{11}=1. So c would be 1/11. So then my final answer would be ln(y) = (\frac{121x^{2}}{2}+1)^{\frac{1}{11}}. I could go further but that's all the question asked for...

Wow. I am stupid. Haha. I can't believe I did not think of that. For some reason the exponent of 11 was messing me up. I'll take the 11th root of each side then put it in the form ln(y) = ... because that is what it asks for. Thanks a lot man. I have being doing differential equations...

Homework Statement Find the solution to the differential equation. Which passes through the point (0,e). \frac{dy}{dx} = \frac{11xy}{(ln(y))^{10}} Homework Equations I can get through the integration part but I am lost when it comes to using the ln rules to find the solution...
