I am not able to calculate the value of C and I want to plot C w.r.t to x,y, t So how to plot the grap

You can use 3d plots for plotting in this scenario. I am attaching a link which explains the use and implementation of various 3d plots.

Thank you for the answer but I am not able to evauate the error of C as x,y,z, are three independent variable and C is dependent variable
