By using definite integral over the intersection points of the two functions.
Area b/w two curves = Integral (f(x)-g(x)) ;

Create the function f(x)= 3/2 sqrt(x^2-4),f(x)= - 3/2 sqrt(x^2-4)
The area b/w the functions would be Integral(f(x) from x [2:3]) + Integral(-f(x) from x [2:3]) as at x=2 hyperbola becomes 0 and x=3 the two functions cross.
Due to symmetry:
Integral(f(x) from x [2:3]) =Integral(-f(x) from x [2:3])
So just calculate Integral(f(x) from x [2:3]) and multiply by 2.
Twice since area is same both above and below x axis.
fun = @(x) 3./2 .* sqrt((x.^2)-4);
ans = 2 .* integral(fun,2,3);
You need to pass function handle in integral().
Also as mentioned in errors use '.^' and '.* ' instead of ^ and * .
Please upovote if you found this helpful.
