Hey,
I'm in Calc I right now, And I learned how to do this, so:
There's two rules to keep in mind when you work these:
Constant rule: You can kick a constant out of the integral to make it easier:
And, you can break it up and integrate the smaller parts, for example:
And remember the antiderivative power rule that Mr. F presented:
for example:
Integrate:
I broke it up into the integration of separate terms.
Then I isolated the constant in each term.
Now we begin integration
Here, we used the antiderivative power rule, as described by Mr. F and this simplifies to:
And that's the integral.
Also, think in terms of fractions for the second problem, it will help enormously. And don't forget the plus C! very important.
Hope this helps!
