Q. Use the limit process to find the area of the region.y=41x3,[2,4]
Set up integral: First, we need to set up the integral for the area under the curve from x=2 to x=4.We use the formula for the definite integral of y=41x3 from x=2 to x=4.Integral setup: ∫2441x3dx
Calculate antiderivative: Next, we calculate the antiderivative of (41)x3. Antiderivative of (41)x3 is (41)⋅(41)x4=(161)x4. Now, we evaluate this from x=2 to x=4.
Evaluate integral: Plug in the upper and lower limits of the integral.Evaluate at x=4: (1/16)(44)=(1/16)(256)=16.Evaluate at x=2: (1/16)(24)=(1/16)(16)=1.Subtract the lower limit evaluation from the upper limit evaluation: 16−1=15.
