Question)

Plot the equation on a 2D graph/chart

An XY GRAPH is required here.

OR

Represent the following on any 3D plot.

This is the equation for a Donut.

R,r are arbitrary constants, denoting the outer and inner radii respectively.

R>r.

(Hint : Use formula nodes in the Mathematics Palette.)

in first equation do we need to plot 2D graph between x and y 'or' we need to take a third variable z and plot.

in this equation R is a constant or what? it will plot a 3d graph of r based on variable x,y and z. right?

hello anoop

regarding the 1st question...yes i think u need to take the 3rd varaiable and equate the sin(x^2+y^2)-cos(xy) to that variable....becoz when u solve the equation it

will  be x^2+y^2-xy=pi/2...which is not possible

To the webcast wednesday team,

even i have doubt in 2nd question...the equation looks similar to the equation of sphere i.e x^2+y^2+z^2=r^2..

if it is so....then r stands for radius which is a constant..& what about the R...does it have any relation with

variables x,y,z or it is also a constant

can you please upload this week webcast

Thank you

hello,

my VIs for this week

I dont know whether i have done justification to the 2nd question.

feedbacks welcome

Hello to all participants,

Thank you for the entries and the replies.

In order to clarify the questions that have been asked,

Question 1 is to be plotted on a XY Graph. The plot has to be between X and Y.

Question 2 is the equation for a 3D Donut.

R is outer radius, r is inner radius.

You make take them to be arbitrary constants, just make sure that R>r.

So the plot will be between X,Y and Z.
