Finding the volume of a cone with a elliptic base! Homework Statement The area of an ellipse is (pi)ab, where a and b are the lengths of the semimajor and semiminor axes. Compute the volume of a cone of height h = 20 whose base is an ellipse with semimajor and semiminor axes a = 4 and b = 6...

Hello Everyone, Below are three questions relating to the integration between curves that have been bugging me for some time now. I know how to integrate between curves. I know how to integrate between x and y, but when given equations like the ones below I am lost as to how to figure out 2...

I switched it to degrees and it worked. Wow. Thanks! What's wrong with radians?!

Homework Statement Evaluate the definite integral of function dx/x^2+1 on interval [tan(3), tan(6)] Homework Equations The Attempt at a Solution The trigonometric inverse function for dx/x^2+1 is arctanx+c. I plugged in tan(3) and tan(6), and subtracted arctan(tan(3)) from...
