Given a point E with a polar coordinate of

∠ °

meaning the radius is 4 and the angle is 120 degree. Counter clockwise rotation of the angle (CCW rotation) is the default rotation

Write polar coordinate in Exponential notation, answer shown below.

e ^j

4 is the magnitude.

2.0944 angle is in radian. Multiply the radian by 57.2958 to get the equivalent in degree (2.0944 x 57.2958 = 120 °)

or divide the degree in polar form by 57.2958 to get the equivalent in exponential form.

Solution using Python in web browser

DEFAULT ROTATION IS COUNTER CLOCKWISE FROM POSITIVE X-AXIS BECAUSE IT CORRESPONDS TO CARTESIAN COORDINATE

Compute its equivalent rectangular coordinate or cartesian coordinate:
