Write a c program to convert from cartesian to polar coordinates?
the equation that convert from cartesian to polar coordinates and vice versa r = sqrt (x*x+y*y); phi = atan2 (y, x); x = r*cos (phi); y = r*sin (phi);
What is turnpike reconstruction problem in data structures?
•Given |D| distances, determine x coordinates for points lying on x-axis-|D|=N(N-1)/2 •Easy to go from points to distances in O(N2) - distances to points is worst-case exponential
How do you determine mouse position in visual basic?

How do you implement a Point class that represents a point in a two dimensional space where a point p is defined by 2 coordinates x and y?
public class Point { public int x; public int y; }
Two forces with magnitudes of 20 pounds and 14 pounds and an angles of 55 degrees between them are applied to an object How do you find the magnitude of the resultant vector?
1) Decide on a position for the vectors; for example, place one of them along the x-axis (from left to right). 2) Making a drawing is sort of optional, but it helps visualize the problem. This might save you from making mistakes. 3) Convert both vectors to rectangular coordinates. The polar-->rectangular conversion, available on most scientific calculators, can help a lot with this. 4) Add the x-coordinate and the y-coordinate of both vectors separately. 5) Convert to polar coordinates (once again, using the corresponding function on your scientific calculator). One of the numbers given, in polar coordinates, is the magnitude of the vector; the other is the angle.
