For this problem, you're given a bunch of integration problems.
00:05
So in order to solve this, we want to make sure that you have all of the integration rules handy.
00:14
And basically, for each of these, we're going to find the rule that goes along with that problem, and then follow that rule to get the answer.
00:23
So, for example, at part a, we're integrating x to the fourth dx.
00:28
That looks a lot like x to the n dx with n equal to four.
00:34
And so the solution is going to be x to the 4 plus 1 or 5 over 4 plus 1 or 5 plus c.
00:44
Moving on to the next one, we have 3 sine x dx.
00:49
Well, that looks like sine x dx with a 3 tacked on in front.
00:53
So that 3 stays right in front.
00:56
And this ends up being minus cosine, so negative 3 cosine of x plus c.
01:05
Again, we can't forget that constant.
01:08
Next is 4e to the x dx.
01:12
That looks like e to the x dx with a four tacked on in front.
01:15
So again, the four stays in front, and the rule tells us that it's just e to the x plus c.
01:25
For part d, we have 6 dx.
01:30
That looks like adx with a being equal to 6.
01:34
So that's just going to become 6x plus c.
01:40
For e, we have 3x dx...
