Thread: cannot simplify this antiderative

f(x) = 17/2 * (squareroot of x)^15 when C=0

I used the rule given by my teacher X^n = 1/(n+1^x) * x^n+1 +C

and end up with:

1/(15/2 + 1^17/2) * x^(15/2 + 1)

I tried simplifying this to: (x^17/2) / (17/2)

is this the function you are attempting to integrate ...



???

Yes.

How did you write it like that?

the math text is created by Latex ... there is an entire forum on this site dedicated to it.

You have misquoted your teacher in two ways:
1) that is NOT equal to x^n so you should not write "x^n= ".
2) there is no "^x" in the first denominator.

The anti-derivative of x^n is [1/(n+1)]x^(n+1)+ C.
In Latex, that is

Click on that formula to see the code for it.

and end up with:

1/(15/2 + 1^17/2) * x^(15/2 + 1)

Of course, you can check if an anti-derivative is correct by differentiating it.
