EinstLab

• One of the personal recommendation topics for school C++ curriculum design, function graphics drawing tools.
  
• Using QT development, it supports trigonometric functions, logarithmic functions, power functions, exponential functions and other elementary mathematical functions, supports polynomials, supports parametric equations, and resolves arbitrary complex expressions.
  
• The expression parsing algorithm uses inverse Polish expressions and stack operations, and the QT plugin qwt is used for drawing.
  
• The poor work of the chicken, everyone laughs.
