<p><alert>Note:</alert> Why study polynomials? What are they good for? Many functions are difficult to calculate without a calculator or computer, for example, trigonometric functions. How <em>DO</em> calculators or computers calculate values for these functions? The answer is based on polynomials which are easier to calculate since they only involve multiplying and addition/subtraction. The graph below shows how the polynomial <m>f(x) = x - \frac{1}{6}x^3 + \frac{1}{120}x^5</m> approximates the function <m>g(x) = \sin(x)</m> for <m>-3 \leq x \leq3</m>.</p>

How <em>DO</em> calculators or computers calculate values for these functions? The answer is based on polynomials which are easier to calculate since they only involve multiplying and addition/subtraction. For example, if you are stuck on a desert island without a calculator, you could calculate a polymomial evaluated at 1.2, but you probably couldn't evaluate <m>sin(1.2)</m>. The graph below shows how the polynomial <m>f(x) = x - \frac{1}{6}x^3 + \frac{1}{120}x^5</m> approximates the function <m>g(x) = \sin(x)</m> for <m>-3 \leq x \leq3</m>.</p>
