    Evaluate the Six Trig Functions of Each Angle

    Use the definitions (not a calculator) to evaluate the six trig functions of each angle. If a value is undefined, state why.

    (1) -pi/3

    (2) 450 degrees

    Why are you asking us to do your work for you?

    $\dfrac{-\pi}{3}\in IV$. It is the same as $\dfrac{\pi}{3}$ with correct signs. Take a right triangle with sides $1,\sqrt3,2$.

    $450^o$ is equiv to $90^o$.
