Power Apps is a suite of apps, services, connectors, and a data platform that provides a rapid application development environment for building custom apps for your business needs. For more details, visit https://docs.microsoft.com/en-us/powerapps/powerapps-overview.
Power Fx is the low-code language used across Microsoft Power Platform. It's a general-purpose, strong-typed, declarative, and functional programming language.
The Tan function returns the tangent of its argument, an angle specified in radians. The General syntax is Tan(Radians).
Reading this article, you can learn how to perform the Tan function from Power Fx using Microsoft Power Apps. Also, you will be able to learn Button control, Label control, and TextInput control in the Power Apps environment.
