Suppose theta is an angle in standard position with terminal army in quadrant III and tan theta = 6/3. Determine the exact calues of the other two primary trigonometric rations.

In quardatn III, x is ______ and y is ________ (r is always positive).

I don't understand how to draw the triangle for reference.

Any help will be greatly appreciated. Thank you.

since both x and y are negative in QIII, then you must have

tan = 6/3 = -6/-3,

so y = -6 and x = -3

now, r = 3sqrt(5)

sin = y/r

cos = x/r

just plug and chug
