What Are The Rectangular Coordinates Given The Polar Coordinates P 4 Pi/4

Given the point (sqrt3,-1) in the rectangular coordinate system.?

Which of the following represents pairs of polar coordinates that correspond to this point?

A (1,pi/4)
B (-1,-pi/4)
C (-2,3pi/4)
D (3,11pi/6)
E (1,-5pi/6)
F (2,-pi/6)

Find the rectangular coordinates for the point whose polar coordinates are given. (4, 2pi/3)?

X = 4*cos(2pi/3) = -2
Y= 4*sin(2pi/3) = 2*sqrt 3

Give the rectangular coordinate of the point p whose polar coordinates are (4,pi/3)?

polar coordinates (r, t) <---> the rectangular coordinate (x = r cost , y = r sint )

What are the polar coordinates of point P whose rectangular coordinates are (4,9)?

I think you mis-categorized this question but to answer it I'd say you have to use the Pythagorean theorem and right triangle trig.
r = sqrt(9^2 + 4^2) = sqrt(97) = 9.85
Ɵ = atan(9/4) = 1.15r

How do I change from rectangular to spherical coordinates and vice versa?

Spherical to Rectangular
(4,pi,pi/2) and (4,pi/4,pi/6)

Rectangular to Spherical(p,theta,phi)
(0,3sqrt2,3sqrt2) and (3,3,-3sqrt6)

These are quite confusing for me, any help on these will be greatly appreciated.

HELP Find the polar coordinates of the point whose rectangular coordinates are given?

x=1
y= sqrt(3)

Since

x = r * cos(theta) and
y = r * sin(theta)

x = r * cos(theta) = 1
y = r * sin( theta ) = sqrt(3)

r = 1 / cos(theta)

sin(theta) / cos(theta) = tan(theta) = sqrt(3)

tan^-1(sqrt(3)) = theta = pi / 3

Since x is positive and y is positive, theta doesn't need to have pi added to it.

r = 1 / cos(pi/3) = 2

(1, sqrt(3)) -> (2, pi/3)

The Cartesian coordinates of a point are given.?

Part a)

Draw (6,-6). You have a right triangle with lengths 6 and 6 so the hypotenuse is 6sqrt2. That is your radius. Since its a 45-45-90 right triangle and the point is located in the 4th quadrant, the theta is - pi/4

polar coordinate is (6sqrt2, -pi/4)

b) Similar to part a but r<0 so r = -6sqrt2 and theta is still -pi/4. (-6sqrt2, -pi/4)

c) Draw (1, sqrt 3) Thus you have a 30-60-90 right triangle with sides 1 and sqrt3. Thus the hypotenuse is 2. Theta is opposite the side length of sqrt3 so theta = 60 = pi/3 Thus the coordinate is (2, pi/3)
