T is a real number and the coordinates of p, which is a point on unicycle is given that corresponds to p.
00:06
So we have to find the exact value of the six trigonometric functions of t.
00:10
But it's carefully.
00:11
The x coordinate is positive and the y coordinate is a negative, which means that it is in quadrant four.
00:15
And the moment i say quadrant four, it tells a lot about the sign of all the six trigonometric function.
00:21
Because in quadrant four, only cos and sec are positive.
00:25
So the point is to root 30 over 11 and minus 1 over 11.
00:30
So definitely the r is not known to us, which we can easily find using the pythagoras theorem.
00:37
So r square will be, okay, r is actually known to us because this is a unit circle, fortunately.
00:44
So this is nothing but one because everything is lying on our unit circle...
