TrigIt

This app lets you apply trigonometry to real-world situations using your phone's camera and sensors. Measure angles and calculate heights of objects like trees or buildings. It generates clear diagrams and saves them for later use.

Highlights
  • Angle measurement tool
  • Inclinometer with camera/gyroscope
  • Adjustable offset for measurements
  • Generates clear diagrams
  • Saves diagrams to camera roll
  • Measures in metric or imperial units

Do you want to make your Mathematics lessons more meaningful? TrigIt allows you to take your students outside of the classroom and apply the mathematics they have learnt to real life scenarios. Measure angles and use trigonometry to calculate the height of different structures around your school or workplace. Do you want to know the height of that tree? Well download TrigIt and you are seconds away from finding out. Features include: - Measure an angle with the built-in angle measurement tool - The built in inclinometer uses your phones camera and gyroscope to ensure you get the most accurate angle measurement - Allows you to add an offset for instances when you don’t measure the angle from the ground. - Generates clear and concise diagrams that are easy for you to understand and interpret. - Saves all diagrams to your phones camera roll so you can access these later on. - Worked solutions available (requires in app purchase). - Includes a full triangle calculator: enter any three values and it solves the rest, including both answers in the ambiguous case. - Measures angles in decimal degrees or degrees, minutes, seconds. - Measures distance in either metric or imperial units.

Graph points to draw unique pictures - Cartesian plane drawing with coordinates is a math-based game that teaches children basic math and essential geometry skills! Coordinate Plane game teaches you to solve real mathematical problems by correctly graphing points together. Cartesian plane named after mathematician Rene Descartes. He created a system of plane graph coordinates, that joins each point on the plane with a number. Coordinates and the Cartesian Plane is an important topic in any school curriculum and it’s required to be taught to all primary school kids. It’s an easy enough topic for little kids to grasp, especially when paired with simple but fun art drawing challenges. After all, joining points together creates pictures, and add to that math coordinates and you’re not only learning math, you're also being an artist! Learn how points are written in (x, y), how they are oriented to the axes, what is a positive and negative directions, how to read coordinates and what it means to join them together. This cool math game will make children learn in a fun and engaging way! Our game is: Completely FREE Simple - locate the points in the cartesian plane and join them to draw millions of pictures! Guarantees Brain fitness, promotes creativity, teaches logical thinking and connects visual aspects with theory! Provides a real IQ boost. Has 3 difficulty levels, with each one having hundreds of different exercises and challenges. Has clean design reminiscent of old-school notepads and simple but engaging graphics. Introduces active learning experience. Challenges kid’s imagination. Learn plane coordinates graph system while playing our fun, free math game!
