  3. 32 nd International Conference on Technology in Collegiate Mathematics VIRTUAL CONFERENCE #ICTCM ABSTRACT • Solving a polynomial equation of degree three or higher, equations involving transcendental functions is not always easy. • We shall use either EXCEL spreadsheet or MAPLE PROGRAMMING to approximate a solution to a desired accuracy. • Here we will use MAPLE PROGRAMMING.

  4. 32 nd International Conference on Technology in Collegiate Mathematics VIRTUAL CONFERENCE #ICTCM DISCUSSION • Finding the zeros or roots of an equation depends on the type of the equation. • We have an already established formula for solving a quadratic equation. • If the equation is a polynomial equation of degree three or higher we might end up using a numerical approximation to approximate the zero of a function.

  5. 32 nd International Conference on Technology in Collegiate Mathematics VIRTUAL CONFERENCE #ICTCM NEWTON’S ITERATIVE FORMULA X(n+1)=x(n) - f(x(n))/f'(x(n)) We terminate the process when |x(n)-x(n+1)| < desired accuracy.

  6. 32 nd International Conference on Technology in Collegiate Mathematics VIRTUAL CONFERENCE #ICTCM EXAMPLE 1 • Use MAPLE Programming and Newton’s Iterative Formula to approximate the zero of the function f(x)=x ^3 +x-1. • Continue the process until the successive iterations differ by less than 0.001.
