    Multivariable Limits

    Homework Statement Find the limit of: (x^2+y^2+2xy)/(x^2+y^2) Homework Equations x = r*cos(theta) y= r*sin(theta) The Attempt at a Solution So what I did was change to polar coordinates. Then it simplifies to: (r^2 + 2r^2cos(theta)sin(theta) )/r^2 Factoring out an r^2 from everything you...

    Eliptical Orbit and Eccentricity

    1. Problem statement The space shuttle is in circular orbit of radius R around the earth. The pilot triggers a brief burn that imparts a forward impulse 'p' to the shuttle. After the burn, the shuttle is in an elliptical orbit which passes back through the point where the burn took place once...
