Find the faction value using coordinates of points on the unit circle Give an exact answer Select the correct choice below and. if necessary, fill in the answer box to complete your choice cot x = (Simplify your answer, including any radicals Use integers or I for any numbers in the expression) The function is undefined

Solution

The equation of a circle is x² + y² = r². Based on this equation and the coordinates of the point, (x,y), where the terminal side of the angle intersects the circle

cotA =x/y

to find the values of the trig functions for angles is to use the coordinates of points on a circle that has its center at the origin.

For ex:- The point (3, 4) is on the circle of radius 5 at some angle A find cot A.

cosA = 3/5

sinA = 4/5

Hence cot A =3/4
