Well I'm looking for suggestions of specific topics that involves Math and Economics but I also asked for a site so that I can search too. :)

I'm currently an undergraduate student and I'm taking BS Mathematics. We're going to start our research this semester. I'm kinda interested in researching about Math and Economics so if you know any good sites for papers/articles about this field, feel free to post it here. Thanks guys! :)

Thank you for this! :) BUMP!

I'm a college student and I'm taking 12 units of math now. I'm having quite a hard time on some topics so I really want to know how should I study for these math topics. Can you also give some other references that I can use? (like the MIT Courseware, Harvard Online Courses, etc.)Here are the...

Super thank you! It's now working. I finally understood the changes you want me to make! Here's my working code: import matplotlib.pyplot as plt from math import * note = " Note: Use 1000 as mass1 and 1e12 as mass2 to get the proper results. " print note i = 0 t = 0 x1 =...

So I'm right to use this one? dt = t + 0.001 but I should also put the code t = t + dt? Also I don't get the idea you're trying to tell about my v_x and v_y. :(

import matplotlib.pyplot as plt from math import * i = 0 t = 0 x1 = [] y1 = [] x = 5 y = 0 bx = 2 by = 0 mass1 = input("input mass 1: ") mass2 = input("input mass 2: ") G = 6.67e-11 bigx = x bigy = y smallx = bx smally = by while i < 10000: i = i+1 while t < 100: offset_x = (x...

import matplotlib.pyplot as plt from math import * i = 0 t = 0 x1 = [] y1 = [] x = 5 y = 0 bx = 2 by = 0 mass1 = input("input mass 1: ") mass2 = input("input mass 2: ") G = 6.67e-11 bigx = x bigy = y smallx = bx smally = by while i < 10000: i = i+1 while t < 100: offset_x = (x...

But what are the directions of the forces here? Towards the other planet and the other one is where? How about my radius, r = sqrt((x-bx)**2 + (y-by)**2), is this the one I should use?

What do you mean no determination? I'm sorry. I'm really confused. I mean how can I set the x and y components of F, a, or v?

Homework Statement We need to plot a two points (representation of planets). One is stationary and one is supposed to move on a circular orbit. We are using Python, Matplotlib and Numpy. We're not getting a circular orbit. We're just getting a line. Homework Equations a = F / mass1...

I got the 1st one already. Only #2 left.

I'm sorry but I don't exactly get it. I'm really having a hard time in Calculus right now. For #1, what is dz? Just a representation for height? and I can't picture properly the tetrahedron I need to slice. For #2, I really don't get it. I'm sorry. I hope you'll still explain it to me.

Homework Statement Find the volume of the described figures 1. A pyramid with height h and base an equilateral triangle with side a (a tetrahedron). 2. Find the volume common to two spheres each with radius r, if the center of each sphere lies on the surface of the other sphere...

@jared: thanks for the advice! :) I will look into that. Yes maybe you're right but we can still wait if there are people who will answer or as you suggested, will give sources. :)
