# Description

Hi Guys,

This is a Smart Worksheet on second order linear differential equations covering both homogeneous and non-homogeneous types and including problems with initial conditions.

There are also some useful de solver tools where you can type in your own problems and obtain the worked solutions so you can check any homework that you have.

There's a PDF file for those who want to work on the sheet independently and an email math que, where you can jot down a questions and append it to an email. If I get time, I will write up a YouTube video solution and send you the link.

All the best with the worksheet and if you have any feedback just give us a buzz.

Cheers,

Mark

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

## 1st Differential Solver Free

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.

The free version of the app can be found at

★ Application areas: Some of the applications areas are:

Physics and sciences

Engineering

Finance and Economics

Industry

Research

★ Who should buy this app?

-Researchers

-Engineers

-Engineering students

-Science students

★ Why buy this app?

- Solves differential equation in quick time

- Reduces time in calculations.

- Reduces effort and time in research.

★ 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)

## Coupled Differential Equations

Upcoming changes:

1) Add a 2nd order coupled differential equation solver

2) Export solution data to txt, or csv format.

---

This app uses the runge kutta 4 algorithm to solve to coupled differential equations of the first order. The results are plotted and can be pinch zoomed. The workflow is streamlined via a custom keyboard and toast messages that help the user towards plotting a solution quickly.

This app is intended for students of science and engineering to get a qualitative understanding of how a coupled 1st order differential system behaves. Future versions of this app will let the user export data, generalize to "N" differential equations and also solve equations of the second order.

Target Audience

Wondering whether Calculus Master is relevant for you? If you fall in any of the following categories, Calculus Master will prove to be an invaluable resource for you!

1. Undergrad students in US/UK/Europe/Australia and other countries taking a Calculus course in any semester.

2. High school students across the world studying Calculus for the first time.

3. Students preparing for particular competitive exams, like the IITJEE Math paper and other Math competitions

How it Works

1. The subject of Differential Calculus is divided into 3 units: (a) Functions and Graphs (b) Limits, Continuity and Differentiation (c) Applications of Derivatives.

2. Each unit is divided into a number of concepts. For example, the unit on Limits, Continuity and Differentiation has concepts like Basic Limits, Exponential and Logarithmic Limits, Trigonometric Limits and so on.

3. You can practice and assess yourself on each concept separately. For example, suppose that you select the concept Basic Limits.

4. When you generate a new session on this concept, the app will select about 10 questions from the available pool of questions and present them to you.

5. As you answer each question, you will be given instant feedback on your response, as well as the detailed solution for that question.

6. Once you complete the session, your cumulative score on that concept will be calculated. This takes into account your scores of past sessions on that concept as well.

7. For questions which you have attempted incorrectly, the app will give you a chance to answer them again in subsequent sessions.

8. When (almost) all questions for a concept have been answered correctly, you can still run that concept in practice mode, in which the app won’t keep track of your scores.

## Inequalities Calculator

Hi Guys,

Enter an inequality that is <, <=, >, >= or = and this works out the solution for you. It basically does just what it says on the tin. So if you have homework that you need to check the answers for, then look no further.

This tool is taken from the selection of tools that appears on my live worksheet app on Inequalities and the Modulus Function, that appears on my wolfram alpha developer page.

Hope it proves helpful.
