plot a graph in intagrl2

syms x y real 
fun = x
y1 = x 
y2 = cos (x)
b= solve (y1==y2);
Volumeofsolid = int(int(fun,y,y1,y2),x,0,b)
x = linspace (0,b,25)
% Please teach me how to assign the value of x to y1
y = linspace (y1,y2,25)
plot(x,y)

[Walter Roberson]

You defined x as a vector of lengh 25. If you substitute that vector into your y1 and y2 formula, then that would be something that you could not linspace()

Answer 1

[Walter Roberson]

I am going to guess:

plot(x,subs([y1;y2]).')

thanks you, i plotted this graph
