Been waiting for an hour, 90 pts to who gets these right 1- find the rectangular coordinates of the point with the polar coordinates (3, 5pi/3) 2- find all polar coordinates of point p where p = (7, pi/3) 3- find the rectangular coordinates of the point with the polar coordinates (1, 1/2 pi) 4- determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°. 5- use your grapher to determine which of the graphs matches the polar equation r = 4 cos 3θ. 6- find all polar coordinates of point p = (6, 31°). (show all work)

(a) the cartesian coordinates of a point in the xy-plane are (x, y) polar coordinates of this point. (-3.11, -2.05) m. find the r3.724 m e=-33.4x your response differs from the correct answer by more than 10%. double check your calculations. (b) convert (r, e) = (4.86 m, 38.70) to rectangular coordinates. y= exercise hints getting started i'm stuck! (a) find the polar coordinates corresponding to (x, y) = (3.1, 1.63) m. 3.50 m (b) find the cartesian coordinates corresponding to (r, e) (4.2 m, 59°).

Let the position of a point p in three dimensions be given by the vector r-cx,y,z) in rectangular (or cartesian) coordinates. the same position can be specified by cylindrical polar coordinates, p, φ, z, which are defined as follows: let p' denote the projection of p onto the xy plane: that is, p' has cartesian coordinates (x, y, 0). then rho and φ are defined as the two-dimensional polar coordinates of p' in the xy plane, while z is the third cartesian coordinate, unchanged. (a) make a sketch to illustrate the three cylindrical coordinates. give expressions for rho, φ, z in terms of the cartesian coordinates x, y, z. explain in words what rho is ("rho is the distance of p from are many variants in notation. for instance, some people use r instead of p. explain why this use of r is unfortunate. (b) describe the three unit vectors rho, φ,2 and write the expansion of the position vector r in terms of these unit vectors. (c) differentiate your last answer twice to find the cylindrical components of the acceleration a ř of the particle. to do this, you will need to know the time derivatives of rho and φ. you could get these from the corresponding two-dimensional results (1.42) and ( 1.46), or you could derive them directly as in problem 1.48.

Write a function that takes in a point in polar coordinates and returns a point in cartesian coordinates. the main part of the program should ask a user for the polar coordinates, call the function and then report the point in cartesian coordinates. you may (or may not) recall that for a point given in polar coordinate (r, theta), the point in cartesian coordinates (x, y) is given by: x
