Assume that alpha is an angle in standard position whose terminal side contains the point (- 2 squareroot 3, 4). Find the exact values of the following functions. sin alpha = (Type an exact answer, using radicals as needed. Rationalize all denominators.) cos alpha = 1 (Type an exact answer, using radicals as needed Rationalize all denominators.) tan alpha = (Type an exact answer, using radicals as needed. Rationalize all denominators.)

Solution

x =-23 , y =4

r=[x²+y²]

r=[12+16]

r=28

r=27

sin = y_/r=4_/(27)=(27)_/7

cos = x_/r=(-23)_/(27)=(-21)_/7

tan = y_/x=4_/(-23)=(-23)_/3
