In doing this, the Integral Calculator has to respect the order of operations. A specialty in mathematical expressions is that the multiplication sign can be left out sometimes, for example we write "5x" instead of "5*x".

For math, science, nutrition, history As there is no way to immediately integrate tan^2(x) using well known trigonometric integrals and derivatives, it seems like a good idea would be writing tan^2(x) as sec^2(x) - 1. Now, we can recognise sec^2(x) as the derivative of tan(x) (you can prove this using the quotient rule and the identity sin^2(x) + cos^2(x) = 1), while we get x when we integrate 1, so our final answer is tan(x) - x + c. Integral Calculator computes an indefinite integral (anti-derivative) of a function with respect to a given variable using analytical integration. It also allows to draw graphs of the function and its integral. Please remember that the computed indefinite integral belongs to a class of functions F(x)+C, where C is an arbitrary constant.

Note that substituting g(x) = x2 + 1 by u will not work, as g '(x) = 2x is not a factor of the integrand. Let us make the substitution x = tan θ then dx by d theta = sec

Suppose our integrand is a rational function of sin(x) and cos(x). After the substitution z = tan(x / 2) we obtain an integrand that is a rational function of z, which can then be evaluated by partial fractions. Theorem: If z = tan(x / 2), then ,, and. and any rational function of xdx becomes a rational function of zdz. Proof. Example
