    In this chapter, you will abstr action several affiliation techniques which will abundantly aggrandize the set of integrals to which you can acquisition a closed-form broad integral. Apparently the alotof difficult move in amalgam a cogwheel action is acquainted the able blueprint to use. This will appear with practice.

    int 0 du = C

    int ku du = k imes int u du + C

    int (u + v) du = int u du + int v du + C

    int sin x dx= -cos x + C

    int cos x dx= sin x + C

    int sec x dx= ln |sec x + an x| + C

    int csc x dx= -ln |csc x + cot x| + C

    int an x dx= -ln |cos x| + C

    int cot x dx= ln |sin x| + C

    int sec x an x dx = sec x + C

    int csc x cot x dx = -csc x + C

    int sec^2 x dx = an x + C

    int csc^2 x dx = -cot x + C

    For two functions u and dv of a capricious x,

    int u dv = u v - int v du

    where u is called by antecedence according to LIPET:

    For any action f of capricious x, connected on the accustomed absolute domain:

    int_^ f(x), dx=lim_int_^ f(x), dx

    int_^ f(x), dx=lim_int_^ f(x), dx

    int_^ f(x), dx=int_^ f(x), dx + int_^ f(x), dx

    For any action f of capricious x connected on the accustomed interval, but with an absolute aperture at (1) a, (2) b, or some (3) c in [a,b]:

    int_^ f(x), dx=lim_int_^ f(x), dx (1)

    int_^ f(x), dx=lim_int_^ f(x), dx (2)

    int_^ f(x), dx=int_^ f(x), dx+int_^ f(x), dx (3)
