Answer:
Over the next few sections we examine some techniques that are frequently successful when
seeking antiderivatives of functions. Sometimes this is a simple problem, since it will be
apparent that the function you wish to integrate is a derivative in some straightforward
way. For example, faced with
Z
x
10 dx
we realize immediately that the derivative of x
11 will supply an x
10: (x
11)
′ = 11x
10. We
don’t want the “11”, but constants are easy to alter, because differentiation “ignores” them
in certain circumstances, so
d
dx
1
11
x
11 =
1
11
11x
10 = x
10
.
From our knowledge of derivatives, we can immediately write down a number of an-
tiderivatives. Here is a list of those most often used:
Z
x
n
dx =
x
n+1
n + 1
+ C, if n 6= −1
Z
x
−1
dx = ln |x| + C
Z
e
x
dx = e
x + C
Z
sin x dx = − cos x + C
