For math, science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, music… The integration of 2x in calculus is equal to x square plus the constant of integration which is symbolically written as ∫2x dx = x 2 + C, where ∫ is the symbol of the integral, dx shows that the integration of 2x is with respect to the variable x and C is the constant of integration. Ex 7. Find integral (2/x^4 + 6x + 5) dx + C; Find the integral of \int xe^{-2x} dx. Since 2 2 is constant with respect to x x, move 2 2 out of the integral. 3 Case III: Integrands containing x 2 − a 2. To integrate (2 x - 1) 2, we are going to use substitution. Math Cheat Sheet for Integrals Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step Derivatives Derivative Applications Limits Integrals Integral Applications Integral Approximation Series ODE Multivariable Calculus Laplace Transform Taylor/Maclaurin Series Fourier Series Fourier Transform. Another method: I = ∫ xe2x (2x + 1)2 dx. Ex 7. x = tan(y) and consequently. We can find the formula for the integral of 2x using various integration rules. This gives that du = 1 dx, or simply du = dx. Therefore, we can replace x + 2 with u and replace dx with du in our integral to get the following: ∫ 1 ( x + 2) 2 d x = ∫ 1 u 2 d u. Then du = −2xdx d u = - 2 x d x, so −1 2du = xdx - 1 2 d u = x d x.
