1st Differential Solver Free

科學工具來解決非線性一階微分方程

Scientific tool/solver to solve “Single Variable Non-Linear First 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 dependent variable at a given value of independent variable (with given initial values of dependent and independent variable).The relationship between dependent and independent can be visualized using the “Plot” function. 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:

- It is always recommended that the user’s 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.

- For example to find value of Y at 10 with initial value of X as 0 and Y as 0 for dY/dX=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 function and initial value of X as 0 and Y as 0 and final value of X as 5. Click “Calculate” to find value of Y at X=5 as “0.45976788”. Now for second step, enter the function and initial value of X as 5 and Y as 0.45976788 and final value of X as 10. Click “Calculate” to find value of Y at X=5 as “0.14979482”.

- When the app returns a “NaN”, either the (i) Y value doesn’t 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).

- Based on capability and limitations of Android system the maximum difference in initial and final X for “Calculate” and “Plot” as fixed as “50” and “30” respectively. For Y at a range greater than 30, use the step process described above. (For larger ranger of 400 and 100 for calculation and plotting, Please try Paid App)
