Question

i need help graphing trig functions

Answer 1

which trig function?

Answer 2

sin and cos

Answer 3

ok so you know that cosine and sine are periodic functions.
where period is 2pi
because after 2pi, the graph repeats itself.
the best way is to plug in points. make sure that your x-axis is in radians and not the usual number line. but the y-axis will have values from -1 to 1 so it is "normal"

plug in some points: 0, pi/4, pi/2, 2pi/3, pi, 5pi/4, 3pi/2, 2pi
and you should get a continuous curve
