I have the same values. Number of contour lines was the problem again. I appreciate all the help!

I did this and got the exact same values, so then I checked my contour and changed how many lines it was showing. Duh. Here's what I have now: I figure this must be right and I just wasn't showing enough lines. One thing that worries me is the mean curvature, should those all be negative...

Thank you for taking the time. Here's what I have for the Gaussian curvature and how I got it: My method for Mean curvature is similar. Should all the Gaussian curvatures be negative? I had in my head that it'd be negative at the bottom and positive at the top, based on a few other surfaces...

I'm hoping someone can help check whether my final contour plots look plausible based on the surface. I haven't done too much differential geometry but I've needed to work with Gaussian/Mean curvature for a simple 3D gaussian surface. Here's an example: (A = 7, a=b=1/(3.5)^2) It's...

Thanks for the recommendations so far. Sounds like you're catching my drift. I wondered these problems myself but thought I'd ask in case some wiz had found a workaround. To be honest I was just hoping there was a common solution to this question that most people here knew about, but it...

I don't mind anything online but I'm not sure whether Wolfram does quite what I'm looking for. My goal really is to insert an equation including multiple physical variables and have the software reduce the equation to its simplest form - perhaps with the option to reverse some of the...

What I mean by this is that I'm looking to see if there's any sort of software out there that has formulae that it "knows" and can reduce/expand back and forth for you. A simple example would be that I type "I*R" and it gets simplified to "V" using this software, or vice versa. I understand...

Homework Statement Homework Equations The Attempt at a Solution http://imgur.com/7TRWjBg I don't really get what it's asking. I don't know how to define a Fourier series when the boundaries for X are between non-multiples of Pi. On top of that, it has one boundary that has 4<x<2Pi. How can...

I appreciate the reply, but these things are a little vague. Could you be more specific?

Particularly, I mean trained skills rather than traits. For example, for a blank student/graduate who knows only physics theory, learning LaTeX would put them a little bit ahead. Then maybe some programming, learning simulation software etc. I'm finishing up my 2nd year in undergraduate right...

I feel as though my ability to properly write up lab books when I do/after I do experiments is really weak. I struggle to analyse the data in a meaningful way. I don't know how to/when to calculate errors properly. I'm near useless when it comes to logarithmic graphs, or inferring any important...

Homework Statement I am trying to find the direction of an E-Field from a given E-Field vector in 3d space. If I have an electric field vector of (-1i, -2j, 3k), the magnitude of the field is sqrt(-1^2 + -2^2 + 3^2) = 3.74, but how do I find the direction? Homework Equations tan(y/x)? The...

Thank you both! I figured the book was old because it was asking me to do this, but I still knew my log knowledge was off somewhere. I'll remember the base 10 thing in future. Thanks again!

A=12^(1/5) Log(A)=(1/5)Log(12) The next part in the book says: Log(A)=0.2158 A=1.644 I don't know how to do this without a calculator, and with a calculator I'm getting 1.24. I'm doing e^0.2158 Can anyone please tell me where I'm going wrong here?Note: this isn't homework, just something...

I'm a 1st year Physics student from the UK that's trying to get informed. After seeing the patent attorney thread, I did a little digging. Not sure how it works in other places, but in the UK you're required to have a degree in science (not a PhD, and as far as I'm aware, there's no requirement...
