Sagot :
Answer:
3dx√x
Step-by-step explanation:
The method of integration by substitution may be used to easily compute complex integrals. Let us examine an integral of the form
ab f(g(x)) g'(x) dx
Let us make the substitution u = g(x), hence du/dx = g'(x) and du = g'(x) dx
With the above substitution, the given integral is given by
ab f(g(x)) g'(x) dx = g(a)g(b) f(u) du
In what follows C is a constant of integration which is added in the final result.
