This question simply tests your ability to recall the definitions of the trig functions. To find all six functions you need to find x, y, and the hypotenuse of the ray going from the origin to P(-4, 6). X=-4, Y = 6, and the hypotenuse can be found from r^{2} = x^{2} + y^{2}

After finding r then use these definitions

sin = y/r

cos = x/r

tan = y/x

csc = r/y

sec = r/x

cot = x/y

r=1

If the terminal side goes through (-4,6)

R cannot be = 1

Find R as Isaac said with Pythagoras's Theorem.
