Integral Cheat Sheet - Web comparison test for improper integrals : Integral of a constant \int f\left (a\right)dx=x\cdot f\left (a\right) take the constant out \int a\cdot f\left (x\right)dx=a\cdot \int f\left. If f(x) ‡‡gx( ) 0on [a,¥) then, 1. If a gxdx ò¥ divg. ∫𝑥−1 𝑥=ln(𝑥) ∫ 𝑥 𝑥 =ln(𝑥) ∫ |𝑥 𝑥=𝑥√𝑥 2 2 ∫ 𝑥 𝑥= 𝑥 ∫sin(𝑥) 𝑥=−cos(𝑥) ∫cos(𝑥) 𝑥=sin(𝑥) trigonometric integrals: Divide [ a , b ] into n subintervals of is a function, f ( x ) ,. Web symbolab integrals cheat sheet common integrals: Then a gxdx ò¥ conv. If a fxdx ò¥ conv. Then a fxdx ò¥ divg.
