Partial Fractions [IB Math AA HL]

This video provides an overview of Partial Fractions, a skill within the IB Math Analysis & Approaches HL course that spans topics like Number and Algebra, Functions, and Calculus. The speaker explains that Partial Fractions simplifies rational functions into a sum of two or more fractions, which aids in integration during calculus. The process involves factorizing the denominator, writing a sum of partial fractions with unknown numerators, and then solving for these numerators using algebraic techniques, including substituting specific values for x to eliminate variables or comparing coefficients. Two examples are demonstrated to illustrate these methods, emphasizing that the decomposed form is easier to integrate.
