$$ =\; 1 $$

What is the Integral of tanx

The integral of tanx concerning x is:

$$ \int \tan(x) dx \;=\; \ln | sec(x) | + C $$

Where c is representing the constant of integration. The derivation of finding the integral of tanx is,

What is the Integral of 0

When integrating a constant value such as 0 which is given, the result is simply the constant times x, plus a constant of integration of C. The integrate calculator gives results in the form of,

$$ \int 0\;dx \;=\; C $$

In simple words, the integral of zero is a constant function. It's independent on the value of x, the results will always be the same constant.

What is the Integral of e^x^2

The integral of ex2 with respect to x is difficult as it does not have a solution in terms of elementary functions. It means you cannot express the integral using the basic algebraic functions but this can be solved in the integral calculus calculator.

However, the integral can be expressed as the power series or by using the special functions. The integral of the above functions can be represented as,

$$ \int e^{x^2} dx \;=\; sum_{n=0}^{\infty} \frac{x^{2n+1}}{n!(2n+1)} + C $$

Here C is the constant of integration.

What is the Integral of 1/x

The integral of 1/x with respect to x is a natural logarithm of the absolute value of x and a constant of integration C which can be represented by calculator integrals as,

$$ \biggr[ \int \frac{1}{x} dx \;=\; ln |x| + C \biggr] $$

This type of integral is generally important because it represents the antiderivative of the function which is 1/x.

What is the Integral of a Constant

The integral of a constant let's suppose k with respect to x is the constant multiplied by x with the constant of integration which is shown on the integrator online as,

$$ \int k \;dx \;=\; kx \;C $$

It’s because the derivative of kx with respect to x is k means that the antiderivative of k with respect to x is kx. The constant of integration here is because the derivative of a constant is zero so any constant could be shown in the original function before differentiation.

What is the Integral of 1/x^2

The integral of 1/x2 is the same as x-2. The integral or antiderivative of xn, where n ≠ -1 so the integration with steps is,

$$ \frac{x^{n+1}}{n+1} $$

Applying this rule, the integral of 1/x2is,

$$ x^{-2} dx \;=\; \frac{x^{-2+1}}{-2+1} + C \;=\; \frac{x^{-1}}{-1} + C \;=\; -\frac{1}{x} + C $$

So the integral is,

$$ -\frac{1}{x} + C $$
