    Study Notes

    Maclaurin Polynomials

    • A polynomial p(x) of degree n that matches the value of a function f and its first n derivatives at x = 0.
    • The formula for the nth Maclaurin polynomial is:
    • pn(x) = f(0) + f'(0)x + (f''(0)/2!)x² + ... + (f(n)(0)/n!)xn

    Taylor Polynomials

    • If a function f can be differentiated n times at x0, the nth Taylor polynomial for f about x = x0 is defined as:
    • Pn(x) = f(x0) + f'(x0)(x-x0) + (f''(x0)/2!)(x-x0)2 + ... + (f(n)(x0)/n!)(x-x0)n

    Sigma Notation

    • A concise way to express the general form:
    • Pn(x) = Σ (f(k)(x0)/(k!))(x-x0)k for k = 0 to n
