Thread: Second Fundamental Theorem of Calculus!!

1. Second Fundamental Theorem of Calculus!!

Find the derivative.

i need help finding this, i dont know how to do it, thanks

2. Generally, you notice that the Derivative and the Integral are very closely related and you simply write down the answer.

Think about $(1+x)^{900}$

3. Hello,

Let F be an antiderivative of f.

Then, $\int_a^b f(t)dt=F(b)-F(a)$

According to it, what can you say ?

4. In a nutshell. The second fundamental theorem of Calculus states:

$\frac d{dx} \int_c^x f(t)~dt = f(x)$

where $c$ is a constant

More generally (By the chain rule), $\frac d{dx} \int_c^{g(x)}f(t)~dt = f(g(x)) \cdot g'(x)$

you have the first case (c = 1), do you see that? your f(t) is $(1 + t)^{900}$, so your answer should be f(x). what would f(x) be?
