A football quarterback throws the football with a speed of 48 feet per second at an angle of 45 degrees upward from the ground. The vector that describes the motion of the football is what?
-------
r = 45
theta = 45%
45(cos45 + isin45)
= (45sqrt2)/2 + 45(sqrt2/2)i
is the complex number form of the vector.
--------
((45sqrt2)/2,(45sqrt2)/2) is the Cartesian form.
