Galois Theory
The number 'e' is a mathematical constant approximately equal to 2.71828, and it serves as the base of the natural logarithm. This constant plays a critical role in various areas of mathematics, particularly in calculus, where it arises in the context of exponential growth and decay, as well as in the computation of compound interest. The transcendence of 'e' indicates that it is not a root of any non-zero polynomial equation with rational coefficients, making it an important figure in number theory and algebra.
congrats on reading the definition of e. now let's actually learn it.
