Example: Let (-4,3) be a point on the terminal side of an angle x in standard position. Find the exact values of x.
Equation: x^2 + y^2 = r^2
so the take the square root on each side to solve
it would be -4squared + 3squared then square root to get r.
your answer is square root of 25 or 5.
x=-4
y=3
r=5
sinx = 3/5 cosx= -4/3 tanx= 3/-4
cscx=5/3 secx= -5/4 cotx=/4/3
