We are simply referring to one of many possible functions whose derivatives equal f For example, x3 is an antiderivative of 3x2 f (g (x)) = tan (2x) ⇒ f' (g (x)) = sec2(2x) = 2sec 2 (2x) Using the chain rule, the derivative of tan (2x) is 2sec2(2x) Finally, just a note on syntax and notation tan (2x) is sometimes written in the forms below (with the derivative as per the calculation above) Just be aware that not all of the forms below are mathematically correct tan2x The integral of tan x, also known as the antiderivative of tan x, is a result that many calculus students and mathematicians memorizeUnfortunately, sometimes you forget it and need to derive it Or maybe, just maybe, you want to prove it to yourself Before we look at deriving the integral of tan x, let's first look at the end result, to see where we're heading

Tan^2x antiderivative
Tan^2x antiderivative-C being a constant So integration of tan^2 (x) would be tanx x c;To integrate tan^22x, also written as ∫tan 2 2x dx, tan squared 2x, (tan2x)^2, and tan^2(2x), we start by utilising standard trig identities to change the form of the integral Our goal is to have sec 2 2x in the new form because there is a standard integration solution for that in formula booklets that we can use We recall the Pythagorean trig identity, and multiply the angles by 2

The Second Derivative Of tan^2x To calculate the second derivative of a function, differentiate the first derivative From above, we found that the first derivative of tan^2x = 2tan (x)sec 2 (x) So to find the second derivative of tan^2x, we need to differentiate 2tan (x)sec 2 (x)The solution is quite simple the antiderivative of 1/x is ln(x)The integral formula of tan is Of so many trigonometric integrals, we will see some examples for tangent integrals Example 1 Integral of tan 2x We substitute the 2 x for u, we derive and we pass dividing the 2 And we replace the terms for u By properties of integrals we extract the 1 2 from the integral Now we apply directly the tangent
