Q. Evaluate the indefinite integral given below.∫x(x−6)6dx
Simplify Integral Expression: Step 1: Simplify the integral expression.We start by recognizing the integral as ∫x(x−6)6dx.
Use Substitution: Step 2: Use substitution to simplify the integral. Let u=x−6, then du=dx. When x=6, u=0. Substitute x=u+6 into the integral. The integral becomes ∫(u+6)u6du.
Expand and Integrate: Step 3: Expand the integrand and integrate term by term.∫(u+6)u6du=∫(u7+6u6)du= ∫u7du+∫6u6du= 81u8+76u7+C
Substitute Back for x: Step 4: Substitute back for x.Replace u with x−6:(81)(x−6)8+(76)(x−6)7+C
