## Solution of exercise 3

If , then .

If , then

Suppose , then

If , then

If u = 6x + 10, then u' = 6

If v' = , then

## Solution of exercise 4

If u = lnx, then

If v' = 1, then v = x

## Solution of exercise 5

If , then

If v' = cos x, then v = sin x

If , then

If v' = sin x, then v = -cos x

## Solution of exercise 6

To calculate A, B and C, we substitute x with −3:

Derive and replace with −3:

x = -3          -20 = B

Derive again:

6 = 2A       A = 3

Also, the coefficients can be found by realizing the operations and equaling coefficients:

-2 = 19 + B

5 = 27 + C

3 = A

B = -20

C = 38

## Solution of exercise 8

t = -1       1 = -2A        A =

t = 1        1 = 2B           B =

=
