WPQ Record vs Touch Trigonometry

Background When welders are used for pressure welding, they must be qualified for the welding process. It is the responsibility of the organization to qualify their welders. Welder performance qualification must address all applicable essential variables for qualification. Applicable Code / Edition & Standards The ranges qualified are in accordance with ASME Section IX 2023 Edition. Utility Design for manufacturer to verify if performance variables are addressed correctly and ranges qualified are in accordance with ASME Section IX and construction Code. This app give ranges qualified for welder performance qualification as well as generate QW-484A form Scope This app address welder performance qualification variables for arc welding processes (OFW, SMAW, FCAW, GMAW, GTAW, SAW, PAW & LBW). Competitive Edge This app is different than those available in the market as this is standalone application, you can operate with any iOS or macOS device and you don't need any active internet connection other than buying the app from App Store. The QW-484A form generated can be stored locally or on cloud so you can access from anywhere and provide access to the welder when needed. Target Audience This app targets pressure items manufacturing organizations, quality control personnel, welders, students who are involved in welding trades and institutions who are doing performance qualification testing. Subscription Requirement: This is paid application, you can download the app from App Store for free however monthly or annual subscription is need before you can use any of the function of this app. Purchase can be made by going to the menu of the application. Terms and condition are also provided there. Terms of Use: This app follow Apple Standard Term of Use (EULA) more information about apple standard Licensed Application End User License Agreement can be found at  https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Finally understand trigonometry. Touch Trigonometry is the most intuitive way to learn the trigonometric functions. Instead of memorizing formulas, you'll see how sin, cos, tan, and the rest actually work—by touching and exploring a live unit circle and graph. Drag your finger around the circle and watch trig functions respond in real time. You'll be amazed at how quickly the "true meaning" of trigonometry becomes clear. Watch the graph on the right trace their values. In seconds, concepts that confused you for years will suddenly click. This app is great for students struggling with trigonometry or anyone looking for a refresher. HOW IT WORKS On the left: an interactive unit circle. Touch anywhere and drag to change the angle θ (theta). A triangle forms showing the relationships between the angle and the trig values. On the right: live graphs of all six trig functions. As you move the angle, dots trace along each curve showing the current value. Touch the graph side to control the angle from there too. It's bidirectional, immediate, and intuitive. No tutorial needed—just touch and explore. Users have told us that they never understood *why* the trig functions existed—until they used this app. From students to the math curious, Touch Trigonometry offers a truly intuitive way to understand one of the trickiest parts of geometry—at your fingertips!
