Yes that is correct. But please do learn to post using symbols.
Why use poor images?

[TEX]\int {\frac{{{x^7} - 1}}{x}dx = \int {\left( {{x^6} - \frac{1}{x}} \right)dx} } = \frac{{{x^7}}}{7} - \ln (|x|) + c[/TEX] gives $\displaystyle \int {\frac{{{x^7} - 1}}{x}dx = \int {\left( {{x^6} - \frac{1}{x}} \right)dx} } = \frac{{{x^7}}}{7} - \ln (|x|) + c$

It is not hard to learn LaTeX coding.

5. Re: Antiderivative

im on an ipad and it does get very hard using the codes.
it takes me literally 30 seconds to get am image posted here...ill try and improve my handwritting.

6. Re: Antiderivative

you should not have the "$\displaystyle \int$" symbol in the final answer where you have already done the integral.

And you should have the "dx" before you have integrated.
