    32.
    tan(θ ) is undefined, pi<= θ <= 2pi

    tan(θ )=sin(θ )/cos(θ )=sin(θ )/0=undefined

    => cos(theta)=0

    θ = cos^-1(0)

    θ = π/2 or θ =90 °

    Thank you for doing 32. My answers are ok for the other two, right?

    Cool. More math later. If I ever go beyond the amount of questions you can daily answer, please tell me.
