Hi I am studing multivariable calculus and I am asked to write down the parametric equation for the conic sections. I know, you are probably thinking " just do a google search". However, it is not totally out there on the web for all the cases. I would please like it if you could write down form the parmetirc equation of a conic section for both the vertical and horizontal categories. Thanks should be an easy thing to do ;)...

How do I solve this problem? Problem 3 For the following differential equation, construct a finite difference approximation around point Xi that is accurate to second order, i.e., O(ha) where h is the step size. Write your answer in terms of Yi+2 = y(xi+2), Yi+1 = y(xi+1), yi = y(xi), and h. 2y + y - y=1

If I am given a problem that says an object moves up and down on a table sinusoidally with a given amplitude of 4 cm and then I am told that the table begins to move up and down very fast leaving the object to eventually leave the table, how would I determine the position in the oscillation that the object left the table and also the frequency that the object left the table? Can you please explain in detail...

Hi! Can someone explain how to to answer the problem? I have tried but I am confused on how to write it? Assume that a competitive market is currently represented by the following supply and demand equations: Qs P 20 Qd 110-0.5P 1. (2 Points) Solve for the equilibrium price and quantity. 2. (1 Point) Solve for the price elasticity of demand. 3. (4 Points) Graph the market equilibrium. Fully label the graph.
