Functie f (x) | Primitieve functie F (x) |
axn | an + 1xn + 1 + c (n ≠ –1) |
1x = x–1 | ln |x| + c |
ex | ex + c |
eax + b | 1aeax + b + c |
gx | gxln (g) + c |
gax + b | 1a · gax + bln (g) + c |
ln (x) |
x ln (x) – x + c |
glog (x) = ln (x)ln (g) |
1ln (g)(x ln (x) – x) + c |
sin (ax + b) |
–1acos (ax + b) + c |
cos (ax + b) |
1asin (ax + b) + c |
sin 2(ax) = 12 – 12cos (2ax) |
12x – 14asin (2ax) + c |
cos 2(ax) = 12 + 12cos (2ax) |
12x + 14asin (2ax) + c |
tan 2(x) = 1 + tan 2(x) – 1 |
tan (x) – x + c |
