This calculus video tutorial explains how to find the integral of tan^5x using integration by usubstitution and pythagorean identities of secant and tangent The integral of tan (x) is ln cos x C In this equation, ln indicates the function for a natural logarithm, while cos is the function cosine, and C is a constant 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\\int \tan^{2}x\sec{x} \, dx\ > <

Tan−1 3 2 x c We now consider a similar example for which a sine substitution is appropriate Example Suppose we wish to find Z 1 √ a2 − x2 dx The substitution we will use here is based upon the observations that in the denominator we have a term a2 − x2, and that there is a trigonometric identity 1− sin2 A = cos2 A (and hence (a2So the required answer is tanxxc Where c is any constantFree math lessons and math homework help from basic math to algebra, geometry and beyond Students, teachers, parents, and everyone can find solutions to their math problems instantly
I thought you needed a trig identity and I guess you gotta substitutes Could anyone just give me a clue (pleaseC being a constant So integration of tan^2(x) would be tanx x c;Enter a function Please write without any differentials such as `dx`, `dy` etc For definite integral, see definite integral calculator Some integrals may take much time Be patient!

Tan^2 integrali$\begingroup$ My answer doesn't tell you what the bottom line is, nor does it tell you how to evaluate the integral of the rational function that results from the substitution, but I think it gives a more detailed account of the substitution itself than the other answers do, and this particular substitution needs a fairly detailed account in order to be properlyIf the integral hasn't been calculated or it took too much time, please write1/2 x ∫(1 cos(2X)) dX = 1/2 x (X 1/2sin(2X)) C It is very important that as this is not a definite integral, we must add the constant C at the end of the integration Simplifying the above equation gives us a final answer ∫sin 2 (X) dX = 1/2X 1/4sin(2X) C

Integration is the basic operation in integral calculusWhile differentiation has straightforward rules by which the derivative of a complicated function can be found by differentiating its simpler component functions, integration does not, so tables of known integrals are often useful This page lists some of the most common antiderivatives\\int \tan^{2}x \, dx\ >

Rather than saying u = sin x, use u = 2x instead Just expand tan u into ##\frac{sin\, u}{cos\, u}## This integral is much easier to solve Expanding sin 2x and cos 2x in terms of sin x and cos x just makes things more complicatedOur calculator allows you to check your solutions to calculus exercises It helps you practice by showing you the full working (step by step integration) All common integration techniques and even special functions are supportedThe Integral Calculator lets you calculate integrals and antiderivatives of functions online — for free!
