Description

From the listing uploaded by “appupdater”.

Generally, differential equations calculator provides detailed solution Online differential equations calculator allows you to solve: Including detailed solutions for: [✔] First-order differential equations [✔] Linear homogeneous and inhomogeneous first and second order equations [✔] A equations with separable variables Examples of solvable differential equations: [✔] Simple first-order differential equations [✔] Differential equations with separable variables [✔] Inhomogeneous linear differential equation of first order [✔] Bernoulli differential equation [✔] Exact differential equations [✔] Linear homogeneous second order differential equations with constant coefficients [✔] Inhomogeneous linear second order differential equations with constant coefficients [✔] Differential equations, allowing reduction of the order [✔] Linear homogeneous and inhomogeneous differential equations of higher order with constant coefficients [✔] Supported all math symbols and functions. For example: sin(x), cos(x), exp(x), tan(x), ctan(x) and other. [✔] Suported complex variables (solve complex equations) The Calculator contain several features: [✔] Several examples [✔] Сorrect input expression errors Examples for solve: y' = x + e^x - 1 y' = 2x/(x^2 - 7)^(1/3) e^y*dy = (x + sin(2x))dx y' = y*(x^2 + e^x) y' - 2*x*y/(1+x^2) = 1 + x^2 y'' + 3*y' = 0 x*y'' - xy' + y = 0 y'' - 2y' = (x^2 + 1)*e^x x*y'' - xy' + y = x^2 + 1 (x^2 - y^2)dx - 2xydy = 0 y'''' + y''' - 5y'' + y' - 6y = x*cos(x) + sin(x) 4y^3*y'' = y^4 - 1

Differential Equations Steps APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is Differential Equations Steps free?

The APK is free to download, but the app offers in-app purchases through Google Play.

Is the Differential Equations Steps APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is d444fdfa32d2f81b110398aba4c5e436.
