Since you say that it is a nonlinear Poisson equation, then I presume it's something like this: del(h(u,r,theta)*del(u))=g(u,r,theta), where f and g are complicated functions of u,r, and theta. (Are r and theta the same as your u and v variables? Or are your u and v ...
In order to solve the Poisson equation in two-dimensions using finite element, I have created the geometry in the pdetoolbox. I can export the decomposed geometry into Matlab and plot it using the pdegplot(g) function. Separately, I have solved the p...

Uses str_replace and rename_all to replace all matching patterns. Uses regex. ▲ BACK TO NAV plyr Tools to solve common problems, like performing the same task over and over. NOTE: This package conflicts with some dplyr commands, so if you're getting weird errors, this might be why. Rep...
Find the equation of the tangent line to the graph of y = (2x + 3)/(3x - 2) at the point (1,5) using the quotient rule. if Y=5X^2+3 then the tangent at X=0, Y=3 is Find the equation of the tangent line at the point (0,0) on the curve given by x = t^2-100 an...
How to calculate factorials by hand? (Explain the method with example) Factorial: A factorial of a number is a mathematics concept, which is highly used in calculating permutations and combinations and even probability of an event. It is product of all numbers from 1 to that number...
Find and classify (as stable, unstable, or semi-stable) all the equilibrium solutions to dy/dx=sin(y) and dy/dx=cos(y). How to find constant of variation How to tell if an equation is time variant or invariant? How do you find the product 1/3 times 7/8? How do you find the ...
plays the role of weight in a least-squares objective. Therefore, to maximize the likelihood, we need to minimize the right-hand side of the equation, and regardless of , the minimum will occur when the sum of the squared deviations takes the minimum value. If there are different sets of...
The regression equation is written as:(9)y=β0+β1x The group of F1 subjects is then coded as -0.5, and the response time for the group of F1 subjects is β0+β1·x1=0.6+(-0.4)·(-0.5)=0.8. The F2 group, to the contrary, is coded as +0.5. By implication, the mean of ...
