I have to input a function where the output is reliant on the y-axis coordinate

Uwind = -75*(1-((75-y)/75)^2)

Is there any way that i can make the y value the y coordinate at any given point along the x axis?

syms y

Uwind = -75*(1-((75-y)/75)^2)

fplot(Uwind)

is this what you are looking for ? if not let know

can you show the code?

ax=-(D/m)*(vx*vx+vy*vy)^0.5*vx;

ay=-g-(D/m)*(vx*vx+vy*vy)^0.5*vy;

vx=Uwind+vx+ax*dt;

vy=vy+ay*dt;

x(i+1)=x(i)+vx*dt+.5*ax*dt^2;

y(i+1)=y(i)+vy*dt+.5*ay*dt^2;

t(i+1)=t(i)+dt;

i=i+1;
