NSU

posted by .

Evaluate (if possible) the function at the given values of the independent variable. Simplify the results. (If an answer is undefined, enter UNDEFINED.)

f(x)=sin x
f(pi)=
f(5pi/4)
f(fpi/30

  • NSU -

    f(pi) = 0
    f(5pi/4) = -1/√2
    dunno what the heck f(fpi/30 is, but
    f(pi/3) = √3/2
