What is the arc length of #f(x)=(1-x)e^(4-x) # on #x in [1,4] #? For objects such as cubes or bricks, the surface area of the object is the sum of the areas of all of its faces. Then, the surface area of the surface of revolution formed by revolving the graph of \(f(x)\) around the x-axis is given by, \[\text{Surface Area}=^b_a(2f(x)\sqrt{1+(f(x))^2})dx \nonumber \], Similarly, let \(g(y)\) be a nonnegative smooth function over the interval \([c,d]\). However, for calculating arc length we have a more stringent requirement for \( f(x)\). As with arc length, we can conduct a similar development for functions of \(y\) to get a formula for the surface area of surfaces of revolution about the \(y-axis\). We'll do this by dividing the interval up into \(n\) equal subintervals each of width \(\Delta x\) and we'll denote the point on the curve at each point by P i. 5 stars amazing app. Let \(f(x)\) be a nonnegative smooth function over the interval \([a,b]\).
