Cylindical Coordinates Infinitesimal Volume The volume, " dV ", is the product of its area, " dA " parallel to the xyplane, and its height, "dz" See the explanantion This is the equation of a circle with its centre at the origin Think of the axis as the sides of a triangle with the Hypotenuse being the line from the centre to the point on the circle By using Pythagoras you would end up with the equation given where the 4 is in fact r^2 To obtain the plot points manipulate the equation as below Given" "x^2y^2=r^2" ">" "x^2y^2 =4 Here are the steps Take the derivative of both sides of the equation with respect to x Separate all of the dy/dx terms from the non dy/dx terms Factor out the dy/dx Isolate dy/dx Some of these examples will be using product rule and chain rule to find dy/dx
