Define area between two curves. Find area of the region enclosed by the parabola y = 2 - x2 and the line y = -x. Define volume integral. Find the volume of solid generated by revolving the region bounded by the curve y2 = x and the line y = 1, x = 4 about the line y = 1. [1+3+6]
Define area between two curves. Find area of the region enclosed by the parabola $y = 2 - x^2$ and the line $y = -x$. Define volume integral. Find the volume of solid generated by revolving the region bounded by the curve $y^2 = x$ and the line $y = 1$, $x = 4$ about the line $y = 1$. [1+3+6]
The area between two curves is the region bounded between two curves in a plane over a common interval. If $y = f(x)$ and $y = g(x)$ with $f(x) \ge g(x)$ on $[a,b]$, then: $$A = \inta^b [f(x) - g(x)] , dx$$ --- Step 1: Intersection points $$2 - x^2 = -x \implies x^2 - x - 2 = 0 \implies (x-2)(x+...
