Question

Find the values of the basic trigonometric function for an angle in standard position passing through (6, 8)

find tanθ and cosθ

Answer 1

(6,8) has opposite side = 8, adjacent side = 6

hypotenuse = sqr(8^2+6^2) = sqr(64+36) =sqr100 = 10

tanx = opposite side/adjacent side = 8/6 = 4/3

tanx = 43/

cosx = adjacent side/hypotenuse = 6/10 = 3/5

cosx = 3/5
