1. ### Research Topic for Math

I'm currently an undergraduate student and I'm taking BS Mathematics. We're gonna 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! :)
2. ### How to study for these maths

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...
3. ### Comp Sci Python Help in Plotting

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...

8. ### Range of this function

f(x) = \frac{1 - x}{\sqrt{5 + 7x - x^{2}}} I know that the range of that function is (-\infty, 0) U (0, +\infty) But how do I get it? I'm having difficulties in isolating x. Can you explain it to me? Thank you. :)
9. ### Real Life Applications of Circular Motion involving Liquids

Guys, our thesis defense is near already. It will be this thursday. I just want to know some more real life applications of Circular Motion involving liquids. The experiment we performed was we placed water inside a bucket then we spin it around. (Vertically) Some water spilled but most of the...
10. ### Acceleration on Lowest and Highest Points (Vertical Circular Motion)

Homework Statement A boy rides a Ferris wheel with a radius of 10.0m. The wheel completes one turn every 30.0s. Find the boy's acceleration at the lowest and highest points on the circular path. Homework Equations \frac{m(V_{max})^{2}}{r}=T-F_{w} The Attempt at a Solution I...
