Read full description

Especially designed for you Math lovers! Solve3Var3Eq is a matrix based app that helps solve problems consisting of 3 equations and 3 variables stated in the following format where n and RHS are numerical values: n(1a)X + n(2a)Y + n(3a)Z = RHS(1) n(1b)X + n(2b)Y + n(3b)Z = RHS(2) n(1c)X + n(2c)Y + n(3c)Z = RHS(3) Solve3Var3Eq also documents the three pivot steps used to arrive at the problem’s solution which enables the user to review each step in the solution process. In addition, a detailed example problem is provided to show a practical way the app may be utilized. Due to space limitations, Solve3Var3Eq excludes comma number separators. In addition, large numbers, especially in pivot table calculations, may exceed available cell size and may be truncated for visual presentation. In some instances where zero is either the divisor or dividend, the result may be an unsolvable equation. In addition, the app rounds to 2 decimal places which may have an impact on your answers. Please note that the app has been designed for educational purposes only. We hope you enjoy Solve3Var3Eq and are open to any constructive comments for improvements. Enjoy!

Fix CNC machine, PLC and drive problems faster. DrMachines is a smart, AI-powered troubleshooting assistant that guides you from your machine to the exact alarm or symptom, then to a clear step-by-step fix, so you can narrow the problem down to one or two likely parts before calling a service engineer. FANUC AND SIEMENS MACHINES: DrMachines covers Fanuc and Siemens machines, two of the most widely used CNC controls in the world. Choose your make and machine, then enter an alarm code or pick a symptom. You get the troubleshooting steps for your exact machine, from the control to the servo drive and spindle amplifier. • Fanuc: Controls, servo drives and spindle amplifiers. • Siemens: Controls and drives. WHAT YOU CAN DO: • Chat with the troubleshooting assistant: describe the problem and it guides you to the right machine, alarm or symptom. • Guided diagnosis: choose Make, Component, Model, Sub-model and Product in a few taps. • Smart search: type an alarm code or describe a symptom. Search understands synonyms and small spelling mistakes. • Alarm details: description, hints and recommended fixes for your machine. • Step-by-step flowcharts: zoomable diagrams where you answer YES or NO, with help text when you are not sure. • Notes, support images and videos where available. • Product Library and problem categories: browse products, alarms, symptoms and fault types. • My Knowledgebase: your own view of the products and content for your account. • "Did this resolve the issue?" feedback on every solution. • Reach an Expert: send a problem to our experts from the app. • Maintenance and safety procedures. FOR COMPANIES AND TEAMS: • Company accounts with roles such as Company Admin, Technical Lead and Viewer. • Admins invite and manage their users on the website. The same account works in the app and on the web. • Try as a guest for a limited time before you sign up. Some content, such as full flowcharts and solutions, requires signing in. SECURE AND SIMPLE: • Sign in with an email code and use Face ID or fingerprint for quick return visits. • Delete your account from inside the app. • Works on phones and tablets.
