Hi, thank you so much for your question.
00:03
Find the coordinates of a point on a circle with radius 10 corresponding to an angle of 50 degrees.
00:10
Okay, so let me draw a circle.
00:18
Okay, maybe it's not very perfect, but i think you can get the idea.
00:25
I'll try my best.
00:57
Okay, so this is a circle.
01:00
And let's see, suppose this radius is 10.
01:10
And we have find the coordinates of a point on a circle with radius 10 corresponding to an angle of 50 degrees.
01:19
Suppose this is an angle, and this angle has a degree of 50.
01:26
Okay, so find a point, find this point.
01:29
This is the point we want to find, the coordinate.
01:32
Okay, so answer to three decimal places.
01:39
So the x -coordinate is equal to the radius times cosine of theta.
01:43
And the y -coordinate is equal to the radius times sine of theta...
