Find the exact values of the trigonometric functions using a point on the unit c

Question

Find the exact values of the trigonometric functions using a point on the unit circle. In this problem, t is a real number and P=(x,y) is the point on the unit circle that corresponds to t. Find the exact value of the indication trigonometric function of t.

Find the Exact Values of the Trigonometric Functions Using a Point on the Unit Circle In the problem, t is a real number and P- (x, y) is the point on the unit circle that corresponds to t. Find the exact value of the indicated trigonometric function of t. 4 165 99)Find sin t. B)41/65 A) 65 C) D) 65 65

Explanation / Answer

(4/9, (65)/9)

tan t=y/x= ((65)/9)/(4/9) = (65)/4

Opposite =(65), adjacent=4

hypotenuse=(65+16)=82=9

sin t=opposite/hypotenuse =(65)/9

Correct option is C
