hello I have a distance/time graph and I want to plot the velocity against distance. I have created the velocity function v:eval v
v =
(36003*cos((33*x)/20 - 383/200))/1000 + (234601*cos((619*x)/500 + 659/500))/6250 + (8542857*cos((3247*x)/1000 + 9293/10000))/1000000 will someone please instruct me how to plot this between a distance of 0 and 500000? GS

v = @(x) (36003*cos((33*x)/20 - 383/200))/1000 + (234601*cos((619*x)/500 + 659/500))/6250 +.......
(8542857*cos((3247*x)/1000 + 9293/10000))/1000000 ;
x = 0:500000 ;
plot(x,v(x)) ;
