You've been asked to find a point located at the coordinate 4 comma 103 pi over 4.
00:09
Well, 4 is your radius.
00:12
We take the absolute value of this number, and that is the length of array or a point on array, four units from the origin.
00:22
103 pi over 4 is your angle measurement.
00:27
But we can simplify 103 pi over 4 into, terms of a circle, we know that a circle starting at zero, going in a counterclockwise motion, and going all the way around the circle, ends at 2 pi.
00:45
So if we take 103 pi, excuse me, 103 pi over 4, and if i convert that to a decimal, i normally don't do that, but in this case it helps us see that we've got 25 .75 pi and we can break that down, excuse me, we can break that down to 24 pi plus 1 .75 pi.
01:20
And the 24 pi is 2 complete circles, or 12 complete circles.
01:27
That leaves us with finding an angle of 1 .75 pi...
