Hello.
I am having some trouble calculating an integral for a given function. Attached is my code so far. I calculated the actual result to be .
Thanks!
syms t x y
>> x = t^3
>> y = t^4
dy =4*t^3
dx = 3*t^2
>> F = (x/y) * (sqrt(dy^2 + dx^2))
F = (16*t^6 + 9*t^4)^(1/2)/t
>> q = int(F, 1, 2)
q = int((16*t^6 + 9*t^4)^(1/2)/t, t, 1, 2)

Replace
q = int(F,1,2)
by
q = int(F,1,2,'IgnoreAnalyticConstraints',true)
