Taylor Series and Maclaurin Series - Calculus 2
The Organic Chemistry Tutor・2 minutes read
To find Maclaurin series, evaluate derivatives at C=1 and C=3 for Ln X and e^x, respectively, simplifying series for each function. The series for cosine X is derived from the series for sine X, involving alternating terms, derivatives, and factorial calculations.
Insights
- The Taylor series for Ln X centered at c=1 involves calculating derivatives of the function at c=1 and using the formula Σ[(x-1)^n/n!] from n=0 to ∞ with alternating signs (-1)^n to write out the series.
- The Maclaurin series for cosine X can be derived from the Maclaurin series for sine X by taking derivatives and manipulating the terms, resulting in a series represented by x to the 2n+1 times negative 1 to the n divided by 2n+1 factorial with alternating signs.
