Integral (Antiderivative) Calculator with Steps

This online calculator will find indefinite integral (antiderivative) of a given function with steps shown (if possible).

  • In general, you can skip multiplication sign, so `5x` is equivalent to `5*x`
  • In general, you can skip parentheses, but be very careful: e^3x is `e^3x` and e^(3x) is `e^(3x)`
  • Also be careful when you write fractions: 1/x^2 ln(x) is `1/x^2 ln(x)` and 1/(x^2 ln(x)) is `1/(x^2 ln(x))`
  • If you skip parentheses or multiplication sign, type at least whitespace, i.e. write sin x (or even better sin(x)) instead of sinx
  • Sometimes I see expressions like tan^2xsec^3x: this will be parsed as `tan^(2*3)(x sec(x))`. To get `tan^2(x)sec^3(x)`, use parentheses: tan^2(x)sec^3(x)
  • Similarly tanxsec^3x will be parsed as `tan(xsec^3(x))`. To get `tan(x)sec^3(x)`, use parentheses: tan(x)sec^3(x)
  • From table below you can notice, that sech is not supported, but you can still enter it using identity `sech(x)=1/cosh(x)`
  • If you get an error, double check your expression, add parentheses and multiplication signs, where needed, and consult the table below
  • All suggestions and improvements are welcomed. Leave them in comments

Solution

Your input: find $$$\int{x \cos{\left (x^{2} \right )} d x}$$$.

Let .

Then (steps can be seen here) and we have that .

Therefore,

Apply constant multiple rule with and :

Integral of cosine is :

Recall, that :

Therefore,

Add the constant of integration:

Answer: $$$\int{x \cos{\left (x^{2} \right )} d x}=\frac{1}{2} \sin{\left (x^{2} \right )}+C$$$.
