Compound Interest: Compound interest refers to the process where both the initial amount and the accumulated interest earn further interest over time. It is calculated based on a fixed period and an interest rate.
Euler's Identity: Euler's identity is a famous mathematical equation linking five fundamental constants: e (Euler's number), π (pi), i (the imaginary unit), 0 (zero), and 1 (one). It demonstrates the beauty and interconnectedness of these mathematical concepts.
Mathematical Constant: A mathematical constant is a specific value that does not change during calculations or formulas. Examples include π (pi) for circles, φ (phi) for the golden ratio, and γ (gamma) for Euler-Mascheroni constant.
