I'm trying to plot these points, please help?

x(10-110) increments of 1

y=(W*L)*(sqrt((h^2)+(x^2)))/(h*x) (for every x value between 10-110)

W=500

L=120

h=50

Everytime I tried plotting x and y not all the y values from the formula would show on the graph, along with there being no line to show the change of Y/X.

x=10:1:110;
W=500;
L=120;
h=50;
y=(W*L)*(sqrt((h^2)+(x.^2)))./(h.*x) ;
figure
plot(x,y)

things to note:

• define the variables BEFORE evaluating them in an equation.

• dot operator for element wise multiplication / division
