As you delve into this guide, you’ll discover invaluable insights that will boost your understanding, sharpen your problem-solving skills, and ultimately lead you to examination triumph.

## Essential Formulas for Functions

### Polynomial Functions

**Standard form:**P(x) = a_n*x^n + a_{n-1}*x^{n-1} + … + a_1*x + a_0**Factor THEOREM:**f(a) = 0 if and only if (x – a) is a factor of f(x)

### Rational Functions

**Standard form:**R(x) = P(x) / Q(x), where P(x) and Q(x) are polynomials and Q(x) ≠ 0**Asymptotes:**- Vertical: x = c if Q(c) = 0
- Horizontal: y = a if deg(P(x)) = deg(Q(x))
- Slant: y = mx + c if deg(P(x)) = deg(Q(x)) + 1

### Exponential and Logarithmic Functions

**Exponential function:**y = a^x, where a > 0 and a ≠ 1**Logarithmic function:**y = log_a(x), where a > 0 and a ≠ 1**Logarithmic Identities:**- log_a(b*c) = log_a(b) + log_a(c)
- log_a(b/c) = log_a(b) – log_a(c)

## Calculus Techniques

### Differentiation

**Rules of differentiation:**- d/dx(x^n) = nx^(n-1)
- d/dx(e^x) = e^x
- d/dx(sin(x)) = cos(x)
- d/dx(cos(x)) = -sin(x)

### Integration

**Indefinite integral:**∫f(x) dx**Definite integral:**∫_a^b f(x) dx**Integration Techniques:**- Integration by substitution
- Integration by parts
- Integration by trigonometric substitution

## Geometry and Trigonometry

### Trigonometry Identities

**Pythagorean theorem:**a^2 + b^2 = c^2**Sine rule:**sin(A)/a = sin(B)/b = sin(C)/c**Cosine rule:**a^2 = b^2 + c^2 – 2bc*cos(A)**Area of a triangle:**A = (1/2) * b * h

### Vectors

**Vector addition:**A + B = [a_1 + b_1, a_2 + b_2, a_3 + b_3]**Scalar multiplication:**cA = [ca_1, ca_2, ca_3]**Vector product:**A × B = [a_2b_3 – a_3b_2, a_3b_1 – a_1b_3, a_1b_2 – a_2b_1]

## Statistics and Probability

### Probability

**Basic probability:**P(A) = number of favorable outcomes / total number of possible outcomes**Conditional probability:**P(A | B) = P(AB) / P(B)**Bayes’ theorem:**P(A | B) = P(B | A) * P(A) / P(B)

### Statistics

**Mean:**μ = 1/n * Σx_i**Standard deviation:**σ = √(1/n * Σ(x_i – μ)^2)**Correlation coefficient:**r = Σ(x_i – μ)(y_i – μ) / √Σ(x_i – μ)^2 * Σ(y_i – μ)^2
