I. ∫ a secθ tanθ√a2(sec2θ − 1) a secθ)dθ. Roughly speaking, an elementary function is a function built up from the familiar functions by using addition, subtraction, multiplication, division, and composition (substitution). Now another integration by parts will do it. Let u = x and dv = ex2 xdx. ∫x2ex2dx.mrofsnarT reiruoF seireS reiruoF seireS nirualcaM/rolyaT mrofsnarT ecalpaL suluclaC elbairavitluM EDO seireS noitamixorppA largetnI snoitacilppA largetnI slargetnI stimiL snoitacilppA evitavireD sevitavireD . ∫x2ex2dx = 1 2 xex2 − 1 2∫ex2dx.

Natural Language. $$ \begin{align Explanation: To integrate x to a power times e to a power, we expect to differentiate the x and integrate the e to a power. Therefore, the integral of x^2 gives the area under the curve of the function f(x) = x 2. It helps … The Integral Calculator solves an indefinite integral of a function. Free definite integral calculator - step-by-step solutions to help evaluate integrals. It may be marginally easier to note at the beginning that cos 2x = 1 − 2sin2 x cos 2 x = 1 − 2 sin 2 x. Use a trigonometric substitution: x = asectheta so dx = asectheta tantheta d theta With a bit of work you can simplify int dx/ sqrt (x^2 - a^2) to int sectheta" " d theta If you know this integral, you can skip the next section.
