# Math Help - Fundamental Theorem of Calculus

1. ## Fundamental Theorem of Calculus

this one seems like it should be easy but i am having trouble and I dont know why.

Intergral from 5 to 7 of ((d/dt)sqrt(5 + 5t^4)) dt

I am not that good at math but wouldn't this be sqrt (5 + 5t^4)? Put t=7 then subtract from thqat the value you get when you put t=5.

3. awww thats it thanks soooooo much

4. That is, after all the "Fundamental Theorem of Calculus" as you titled this thread!

$\int_a^b \frac{df}{dx} dx= f(b)- f(a)$.
