                If θ is an angle in standard position and its terminal side passes through the point (20,-21), find the exact value of sec(θ).

    so x = 20 , y = -21 , which is in quad IV
r^2= 400+441 = 841
r = √841 = 29
then cos Ø = 20/29
sec Ø = 29/20 = 1.45

    If θ is an angle in standard position and its terminal side passes through the point (20,21), find the exact value of \cos\thetacosθ in simplest radical form.
