Integral of 1 2x

the derivative of x 2 is 2x, and the derivative of x 2 +4 is also 2x, and the derivative of x 2 +99 is also 2x, and so on! Because the derivative of a constant is zero.5, 6 Integrate the function (1 − 𝑥2)/(𝑥(1 − 2𝑥)) ∫1 (1 − 𝑥2)/(𝑥(1 − 2𝑥)) 𝑑𝑥= ∫1 (1 − 𝑥^2)/(𝑥 − 2𝑥^2 ) 𝑑𝑥 So if we divide our function by that constant, we'll have our antiderivative: d/dx (1/2) ln (2x+1) = (1/2) * d/dx ln (2x+1) = (1/2) * 2 * [1/ (2x+1)] = 1/ (2x+1) Then by the fundamental theorem of calculus, the integral of 1/ (2x+1) on the interval [a,b] is equal to (1/2) ln (2b+1) - (1/2) ln (2a+1).
