Important Formulation for Capabilities
Polynomial Capabilities
- Normal kind: P(x) = a_n*x^n + a_{n-1}x^{n-1} + … + a_1x + a_0
- Issue THEOREM: f(a) = 0 if and provided that (x – a) is an element of f(x)
Rational Capabilities
- Normal kind: R(x) = P(x) / Q(x), the place 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 Capabilities
- Exponential operate: y = a^x, the place a > 0 and a ≠ 1
- Logarithmic operate: y = log_a(x), the place 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 Strategies
Differentiation
- Guidelines 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
- Particular integral: ∫_a^b f(x) dx
- Integration Strategies:
- Integration by substitution
- Integration by elements
- 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)
- Space 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 Likelihood
Likelihood
- Fundamental chance: P(A) = variety of favorable outcomes / whole variety of potential outcomes
- Conditional chance: P(A | B) = P(AB) / P(B)
- Bayes’ theorem: P(A | B) = P(B | A) * P(A) / P(B)
Statistics
- Imply: μ = 1/n * Σx_i
- Normal 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
