Интеграл (3e^x - 4cos x +3x^2 - 4x + 2) dx

Question

Интеграл (3e^x - 4cos x +3x^2 - 4x + 2) dx

Answer 1

∫(3e^x - 4cos x +3x^2 - 4x + 2) dx=3e^x-4sinx+3x^3/3-4x^2/2+2x+C=3e^x-4sinx+x^3-2x^2+2x+C

Answer 2

S(3eˇx-4cosx+3xˇ2-4x+2)dx=3eˇx-4sinx+3.xˇ3/3-4.xˇ2/2+2x+c=
=3.eˇx -4.sinx +xˇ3-2.xˇ2+2x+c
Seˇxdx=eˇx (+c),Scosx dx = sinx (+c),Sk.dx =k.x (+c),
