Look at the given expression,
![]() | ( | 4x | ![]() | ![]() 2 | + | 3x 1.1 6) | dx |
The first rule to remember is this: constant coefficients (such as the 4 in front of the x, the (1/2) in front of the x2, and the 3 in front of the x
1.1) always "go along for the ride." In other words, we can just copy them over when taking the antiderivative. Therefore, the first term is
![]() | 4x dx | = | 4 | ![]() | x dx | = | 4 | ![]() 2 | + C | = | 2x2 + C. |
Now look at the second term.
![]() | ![]() 2 | dx |
is the same as
![]() | 1![]() 2 | x2 | dx | = | 1![]() 2 | ![]() | x2 | dx | = | ![]() 2 |
![]() 3 |
+ C | = | ![]() 6 |
+ C. |
That takes care of the second term. The third term is
![]() | 3x 1.1 dx | = | 3 | ![]() | x 1.1 dx | = | 3 | 1.1+1)![]() 1.1+1) | + C | = | 3x 0.1![]() 0.1 | + C. |
Finally, the last term is
![]() | 6 dx | = | 6x + C. |
Putting them all together gives:
![]() | ( | 4x | ![]() | ![]() 2 | + | 3x 1.1 6) | dx |
