Q. Find ∫02f(x,y)dx and ∫03f(x,y)dy.f(x,y)=11yx+2∫02f(x,y)dx=□∫03f(x,y)dy=□
Given Function and Integral: We are given the function f(x,y)=11yx+2. We need to find the integral of this function with respect to x from 0 to 2. Let's denote this integral as Ix.Ix=∫0211yx+2dxSince y is treated as a constant with respect to x, we can pull it out of the integral.Ix=11y∫02x+2dxNow we need to find the antiderivative of x+2 with respect to x.Let x1, then x2.The integral becomes:x3The antiderivative of x4 is x5.So, x6 evaluated from x7 to x8.
Pulling Out Constants: Now we evaluate the antiderivative at the upper and lower limits of integration. Ix=11y×32×[423−223]423=(22)23=23=8223=23=8=22So, Ix=11y×32×[8−22]Ix=11y×32×[8−22]Ix=322y×[4−2]
Finding Antiderivative of x+2: Next, we need to find the integral of the function f(x,y) with respect to y from 0 to 3. Let's denote this integral as Iy. Iy=∫0311yx+2dy Since x is treated as a constant with respect to y, we can pull x+2 out of the integral. f(x,y)0 Now we need to find the antiderivative of f(x,y)1 with respect to y. The antiderivative of f(x,y)1 is f(x,y)4. So, f(x,y)5 evaluated from f(x,y)6 to f(x,y)7.
Evaluating Antiderivative at Limits: Now we evaluate the antiderivative at the upper and lower limits of integration.Iy=x+2×(211)×[32−02]32=9So, Iy=x+2×(211)×9Iy=x+2×(299)
