Question 852879
Given tan 0=3/5 with the angle located in the first quadrant, find the remaining five trigonometric ratios.
y = 3 ; x = 5
So r = sqrt(9+25) = sqrt(34)
------------------
sin = y/r
cos = x/r
tan = y/x
csc = r/y
sec = r/x
cot = x/y
==========================
convert to radian measure:
(a)18(degree) = 18(pi/180) = pi/10
--------------------------
(b)200(degree) = 200(pi/180) =  (10/9)pi
-----------------------------------
Cheers,
