console.log(evaluate("(2 + 3) * 4"));         // 20
console.log(evaluate("2 ^ 10"));              // 1024

// Trigonometric functions
console.log(evaluate("sin(pi / 4)"));         // 0.7071067811865476
console.log(evaluate("cos(0)"));              // 1

// Logarithmic functions

// Variables
const scope = {};
