I have the following mathematical function f=5sin(x), I use the int(f) to obtain the integral of my expression. Is there a way for me to evaluate the result of the integral at a specifc value, lets say 4,32,

syms x
f = 5*sin(x)
fint = int(f,x,0,x)
a = 4.32
fa = subs(fint, x, a)
If you are expecting a decimal value, then you are wanting to get an approximation at the location, rather than the value at the location.
double(fa)
