Quick Start

from mathhook import Expression, symbol

# Create symbols
x = symbol('x')
y = symbol('y')

# Build expressions
expr = x**2 + 2*x + 1

# Simplify
simplified = expr.simplify()
print(simplified)  # x^2 + 2*x + 1

from mathhook import solve
solutions = solve(x**2 - 4, x)
print(solutions)  # [2, -2]

# Calculus
derivative = expr.diff(x)
print(derivative)  # 2*x + 2

integral = expr.integrate(x)
print(integral)  # x^3/3 + x^2 + x

Expression Creation

Basic Expressions

from mathhook import Expression, symbol

# Integers
num = Expression.integer(42)

# Floats
pi_approx = Expression.float(3.14159)

# Rationals (exact fractions)
half = Expression.rational(1, 2)

# Symbols
x = symbol('x')
y = symbol('y')

# Arithmetic operations
sum_expr = x + y
product = x * y
power = x ** 2
quotient = x / y

Operator Overloading

Python bindings support natural mathematical notation:

from mathhook import symbol

x = symbol('x')
y = symbol('y')

# All standard operators work
expr = (x + y) * (x - y)  # Difference of squares
expr = x**2 + 2*x + 1      # Polynomial
expr = (x + 1) / (x - 1)   # Rational function

Functions

from mathhook import sin, cos, tan, exp, log, sqrt

x = symbol('x')

# Trigonometric functions
trig = sin(x)**2 + cos(x)**2  # = 1

# Exponential and logarithmic
exponential = exp(x)
natural_log = log(x)
log_base_10 = log(x, 10)

# Square root
root = sqrt(x**2 + 1)

Constants

from mathhook import pi, e, I, oo

# Mathematical constants
circle_area = pi * r**2
euler_identity = exp(I * pi) + 1  # = 0
limit_expr = 1 / oo  # = 0

Algebraic Operations

print(expr.simplify())  # 1

# Rational expressions
expr = (x**2 - 1) / (x - 1)
print(expr.simplify())  # x + 1

Expansion

from mathhook import symbol

x = symbol('x')

Type Hints

MathHook provides full type hints for excellent IDE support:

from mathhook import Expression, Symbol
from typing import List, Union

def quadratic(a: Union[int, float], b: Union[int, float],
              c: Union[int, float], x: Symbol) -> Expression:
    """Create a quadratic expression."""
    return a*x**2 + b*x + c

def roots(expr: Expression, var: Symbol) -> List[Expression]:
    """Find roots of an expression."""
    from mathhook import solve
    return solve(expr, var)

Examples

Quadratic Formula

from mathhook import symbol, solve, sqrt

x = symbol('x')
a, b, c = 1, -5, 6

solutions = solve(equation, x)
print(f"Solutions: {solutions}")  # [2, 3]

Taylor Series Approximation

from mathhook import symbol, sin, cos

x = symbol('x')

# Approximate sin(x) with Taylor series
sin_approx = sin(x).series(x, 0, 10)
print(sin_approx)

# Compare with exact value
print(f"sin(0.1) exact: {sin(0.1)}")
print(f"sin(0.1) approx: {sin_approx.subs(x, 0.1)}")

Matrix Eigenvalues

from mathhook import Matrix, symbol

# Symbolic matrix
t = symbol('t')
A = Matrix([
    [t, 1],
