2nd Differential Solver Free play online

Scientific tool/solver to solve Single Variable Non-Linear Second Order Ordinary Differential Equations. The app is very useful for engineers, scientists, economists to study the behaviour of a non-linear system encountered in practical problems. The app computes the value of Y and dY/dX at any given value of X (with given initial values of X, Y and dY/dX). The relationship between X-Y and X-dY/dX can be visualized using the Plot Y and Plot yDot functions respectively. The results along with the Plot can be sent to any e-mail id by using Send e-mail option. The app has a very rich and is very user-friendly UI (user interface). The results can be sent to any e-mail id by using Send e-mail option in main menu.
Please read the Equation format specified in help before attempting to solve complex non-linear equations.

Tips and Notes:
\tIt is always recommended that the users uses as smaller difference in final and initial X as possible to get Higher accuracy and Better Resolution in Plot. This can be done using the step process as described below.
\tFor example to find value of Y at 10 with initial value of X as 0, Y as 0 and yDot as 0 for d2Y/dX2 =Cos(X)*Sin(X). To get higher accurate results split the range of 10 into 2 steps (0 to 5 and 5 to 10). For first step, enter the equation and initial value of X as 0, Y as 0, yDot as 0 and final value of X as 5. Click Calculate to find value of Y and yDot at X=5 as 1.3180026397909919 and 0.45976788267781876 respectively. Now for second step, enter the equation and initial value of X as 5, initial value of Y as 1.3180026397909919, initial yDot as 0.45976788267781876 and final value of X as 10. Click Calculate to find value of Y and yDot at X=10 as 2.3858818461857414 and 0.1479794846781928.
\tWhen the app returns a NaN, either the (i) Y and dY/dX value doesnt exist at the final X or (ii) range is too large, try reducing the difference in initial and final X and use the step process described above (this is especially needed for functions with large curvature like tan and log).
\tBased on capability and limitations of Android system the maximum difference in initial and final X for Calculate, Plot and Plot yDot as fixed as 50, 30 and 30 respectively. For Y and dY/dX at a range greater than 50, use the step process described above. (For larger ranger of 200 and 100 for calculation and plotting, Please try Paid App)
