Hello Steven,
FullSimplify[D[Integrate[Sec[t],
{t, 1, x^4}], x]]
yields:
4*x^3*Sec[x^4]
Satisfied?
Best regards,

Betreff: [mg49573] Fundamental theorem problem
I input the command: D[Integrate[Sec[t],{t,1,x^4}],x] expecting to get
4x^3 Sec[x^4] but instead got a fairly complicated result that doesn't
resemble what one would expect from the Fundamental Theorem of Calculus.
What am I doing wrong? Help!
