This is strange because I got this to work before with the variable x but when I changed the variable x to x1 it stopped working and has not worked since even changing it back to x. I dont know what I did or how to solve this.
d1 = (25*cosd(30)/9.81*(25*sind(30)+sqrt((25*sind(30))^2+2*9.81*3.5)))
y1 = (x1*tand(30)-(1/2)*9.81*x1.^2/((25*cosd(30))^2))
x1 = linspace(0,d1,200)
plot(x1,y1)

You are using x1 in your calculation for y1 before you ever define x1. Flip the order of those two lines.
It might have worked before if you are running this as a script (in the base workspace) and you had a previously-existing definition for "x".
