Derivation - course work c++

The application can calculate the derivative of a particular value of x Allowed operations: +, -, *, ^ To enter an expression you can use:

  1. Your keybord
  2. Application's button

Operation that can be used:

  1. +, -, *, ^ (degree)
  2. AC - clear field for entering an expression
  3. Get result - estimate polynomial derivative in concrete value of x The coefs of polynomial are only real type
