math

Basic idea

The study of structure, quantity, change, and space using formal reasoning. Subdivides into algebra (structure), analysis (change), geometry/topology (space), logic/set theory (foundations) and discrete math.

Key formulas

• Euler’s identity: $e^{i\pi}+1=0$
• Pythagoras: $a^2+b^2=c^2$
• Fundamental theorem of calculus: $\int_a^b f'(x)\,dx = f(b)-f(a)$
• Binomial theorem: $(x+y)^n=\sum_{k=0}^{n}\binom{n}{k}x^{n-k}y^k$
