Question

I know the answer of a and b but I don't know hoe to do c

dy a) Find- if y = ax +b cx+d b) By using changes of variable of the form (*) show that: dx=-in 3--In 2 4 c) Using the ideas

math calculus

Answer 1

Answer #1

c) Here note that

$x+1 +3 dx (x+ 3)2 x+2 +3 dx (x + 3)2$

$Intdt = t Int _ t + C$

We have

$x2 + 3x 2 (X + 3)2 (x + 3)2 (x + 3)2 o (x + 3)2 X 3 1x1 1x 1, X 1 (x + 3)2 2x + 3 2x 3 0 X 3$

$x2 3x 2 (x + 3)2 3 3, 3 2 2, 2 Jo (x+3)2$

Here,

$x+1 x+2 x+3 X +1 3 3. 3 2 22 X +1 4 4 4 3 33$
