Thanks for the response, i solved it. Since one of the demands was that y>=0 i broke the solid down into two parts, one from x=0 to x=sqrt(2) which is before the lower function crossed the x-axis f(x)=0. The other part was from where the lower function crosses the x-axis f(x)=0 to where the...

Sorry if i made any language errors, english is not my first language. Question: An area in the first quadrant (x=>0,y=>0) is limited by the axis and the graphs to the functions f(x)=x^2-2 and g(x)=2+x^2/4. When the area rotates around the y-axis a solid is created. Calculate the volume of...

Sorry if i made any language errors, English isn't my first language. Question: The limited area in the plane is created when the space between the line y=1 and the graph to the function f(x)=3*x/(x^2+1) rotates around the y-axis. Calculate the volume of the solid.I want to sum up all the...
