how do I adjust the x y intercept?

Hi

Given this curve

How do I make it so that it looks like

i.e. so that x and y intersect at x=y=0

also if the only x values that I want to see, are x=0, x=90, x=180

Thanks

Hello,

The first plot that you mentioned is already at x=y=0. Use xgrid() command to plot grids for better visualization. Also, note that the sin() accepts arguments in radians. If you want to give inputs in degrees say 0, 90, 180, use sind() function. See the code below.

clf() t=0:1:360; y=sind(t); plot(t,y)
