    it's easy first you need to know that on x axis ( horizontal axis) we plot Phase change and on Y axis we plot the magnitude of that respective Change.

    at 0. Cos (0)=1 at pi/4 Cos (pi/4)=0 at pi/2 cos (pi/2)=-1 at 3pi/2 cos (3pi/2)=0 at 2pi cos(2pi)=1

    @alekos desmos is awesome, but every time I graph my x and y values are just too huge. :/

    as far as I know the x,y values can be adjusted using the settings and changing the step value

    I'm not allowed to use graphing calculators for my math either. ..even though I got used it during my community college years, but once I've practiced a lot without the calculator, it didn't bug me that much.
