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

The simultanous equation calculator helps you find the value of unknown varriables of a system of linear, quadratic, or nonlinear equations for 2, 3,4 or 5 unknowns A system of 3 linear equations with 3 unknowns x,y,z is a classic example This solve linear equation solver 3 unknowns helps you solve such systems systematically 25 T Evaluate Green's theorem using a computer algebra system to evaluate the integral \(\displaystyle \int_C xe^y\,dxe^x\,dy\), where \(C\) is the circle given by \(x^2y^2=4\) and is oriented in the counterclockwise direction 26 Hi Zach Since y^2 = x − 2 is a relation (has more than 1 yvalue for each xvalue) and not a function (which has a maximum of 1 yvalue for each xvalue), we need to split it into 2 separate functions and graph them together So the first one will be y 1 = √ (x − 2) and the second one is y 2 = −√ (x − 2)
