Vi kan bestämma arean med en integral, men först måste vi ta reda på vilka x-värden som avgränsar området. I det här fallet motsvaras dessa av funktioneras

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.

The integral of tan(x) can be solved by rewriting the equation as the integral of sin(x)/cos(x) dx, and then using the integration technique called substitution. Using substitution, the value u is used in place of sin(x), and the value for the derivative of u, du, is found to be -sin(x) dx.

I had a calculus final yesterday, and in a question we had to find a primitive of $\\tan(x)$ in order to solve a differential equation. A friend of mine forgot that such a primitive could easily be We recall a standard integration usually found in formula booklet for sec 2 kx. As you can see, there is a straight solution for this integration.
