Thank you.

Hello, I want to create my own physics engine. Basically, I want to create a visual environment where a user can create any object that he desires and run a simulation of that object like it were in a real world. Basic physics engines are used popularly in games like Angry Birds. My...

Well, the mass can be easily measured by balancing torque once you locate the center of mass of the head. The trouble is thus the center of mass.

I'm more into an integrated science course, so IISc suits me more than CMI (To be precise, I want B.Sc, not a B.Math). But I would appear for the INMO exam though. Thanks a lot for the information. Do give me the study material! By the way, if you're really into Maths, ISI Bangalore is also a...

Hi. I'm a twelfth standard student from India. (Education system is very different here from other place, be well acquainted before posting). I'm preparing for IIT JEE. But getting into IIT is not my real goal (it's a backup plan I guess). I want to get into a science college like IISc...

Okay, first of all. I know it's too late to answer but I believe I got it. Let z=x+iy,a=p+iq and w=u+iv But on a real line, z=x (y=0 is the line) Hence z = x w=u+iv=f(z)=f(x+i0)=f(x) =\frac{x+p-iq}{x+p+iq} Now as you can see (and also prove) that |w|=1 no matter what x,p and q are.

Hmmmm. For the first question: Let w= u + iv Let z = x + iy Hence |z|=x^{2} + y^{2} = 3 ( I hope you understand how this works. It's basically finding the distance of the point (x,y) from origin on a cartesian plane which is called an Argand plane for complex numbers) Now w=\frac{6}{z}...

It's a sphere! Assuming this to be a case of rolling without slipping, the the total energy in the sphere is \frac{7}{10}mv^{2} Here's how: Total energy = Translational Kinetic energy + Rotational kinetic energy = \frac{1}{2}mv^{2} + \frac{1}{2}I\omega^{2} (m = mass v = velocity...

Thanks a lot.

But the answer is zero. Also can you suggest me some good self-study material to learn complex calculus? I'm good at real number calculus, and I started reading this book called 'Complex Variables Demystified' by David McMohan. But it's the only one I have.

Homework Statement I'm a newbie at complex analysis. Find: lim \frac{\bar{z}^{2}}{z} z→0 2. The attempt at a solution L'Hospital rule gives the answer in no time. But how do you solve without it?

So no one's interested after all. Alright, I understand.

I took 60 because the other 40 were a part of a case study which involved people of similar age group all studied with a single type of test sequence. The subjects were made to listen to 10 tones and after they're done listening a test was conducted for 5 tones which they had to identify...

Are you serious? I've worked really hard for this and if you can't respect that at least don't make fun of it.

A research on perception of pitch Homework Statement I've been working on a project. It's regarding the human perception of sound. I basically tested around 100 human subjects and made a report of it. The data of 60 individuals is in "google_science_fair..zip" attached with the post...
