WebThe most common use of the eval function is to evaluate an expression e at a given point x=a. For example, eval (x^2+3*x+2,x=1) evaluates the polynomial x^2+3*x+2 at the point obtaining 6. • You can enter the command eval using either the 1-D or 2-D calling sequence. For example, eval (x^3 + 3*x + 2, x=1) is equivalent to . • WebThe problem of evaluating an expression can be broken down into 3 steps: Tokenizing the expression (turning the input into a list of symbols and numbers) Converting the tokens to postfix format (where the operator goes after the 2 operands) Evaluating the postfix expression with a stack machine (calculating the answer) Tokenizing the expression
