Operations

Operations:

This scientific calculator can perform the following operations which are listed below:...

Approach:

First create an HTML layout featuring an input field and buttons for numeric and operational input. Now use CSS to design the table for all the input values like number,sin,= etc. External math.js library is imported for mathematical evaluation. Use JavaScript functions to manage key calculator actions, including handling button clicks and updating the display. Implement trigonometric functions (sin, cos, tan) to handle both degrees and radians using standard JavaScript. Implemented error-handling mechanisms to handle invalid expressions and display an “Error” message when necessary. Include buttons for special constants such as pi and the mathematical constant e directly through JavaScript. Add buttons for common operations like clearing the display (C), backspacing, and performing factorial calculations (!). The calculator evaluates expressions using math.js and displays the result in the input field....
