Calculate

Introduction

The Calculate Activity is an infix-notation graphing calculator. Type an expression or select components from the toolbars, and press Return to evaluate it.

More Info: Activities/Calculate

What is new for users

The new toolbar design has been added to Calculate. Plot, degree/radians, scientific notation, and precision buttons are always visible in the main toolbar (as well as the Stop button).

The activity toolbar is used to name the session, share, and keep a version.
The edit toolbar is used for copy and paste
The algebra toolbar is used for common functions such as square and square root
The trigonometry toolbar is used for trigonometry functions: sin. cos, etc.
The boolean toolbar is used for operators: and, or, and not
The constants toolbar is used for constants pi, e, Euler's Constant, and the Golden Ratio
