Trigonometry

Solve the equation for solutions in the interval [0, 360).
tan 4x = 0

Which is the correct answer?

x = 33, 57, 147, 237, 327
x = 0, 90, 180, 270
x = 0, 45, 90, 135, 180, 225, 270
x = 0, 45, 90, 135, 180, 225, 270, 315

Solution Preview

tan(4x)=0= tan(180k)
4x=180k ---> x= 45k.

Now starting from k=0, we check to see how many k's ...
