Question

If the point (3/5,4/5) corresponds to an angle in the unit circle, what is csc x?

Answer 1

Find csc x

Ans: 1.25

Explanation:

Given point `M (3/5, 4/5)` the extremity of the arc x on the trig unit circle, `tan x = y/x = (4/5)/(3/5) = 4/3` --> `x = 53^@13`
sin x = sin 53.13 = 0.8
`csc x = 1/sin x = 1/0.8 = 1.25`
