Terms in this set (20)
x = r cos θ, y = r sin θ, r = √(x² + y²), θ = tan⁻¹(y/x)
dy/dx = (f'(θ) sin θ + f(θ) cos θ) / (f'(θ) cos θ - f(θ) sin θ)
L = ∫αβ √{(f'(θ))² + (f(θ))²} dθ
A = ½ ∫αβ (f(θ))² dθ
z = r (cos θ + i sin θ) where r = √(a² + b²), a = r cos θ, b = r sin θ
Multiplication corresponds to multiplying magnitudes and adding angles; division corresponds to dividing magnitudes and subtracting angles in polar form.
Two vectors ⃗u and ⃗v are orthogonal if and only if ⃗u · ⃗v = 0
Two vectors ⃗u and ⃗v are parallel if and only if ⃗u × ⃗v = ⃗0
S = ∫ab 2π f(x) √{1 + (f'(x))²} dx
∫ u dv = uv - ∫ v du
Use x = a sin θ, then dx = a cos θ dθ
Use x = a tan θ, then dx = a sec² θ dθ
Use x = a sec θ, then dx = a sec θ tan θ dθ
The error |S - SN| in approximating an alternating series by its first N terms is less than or equal to the absolute value of the (N+1)th term.
f(x) = Σl=0^∞ (f⁽ˡ⁾(a) / l!) (x - a)ˡ
tan⁻¹(x) = Σk=0^∞ (-1)^k x^(2k+1) / (2k+1)
Volume = ∫ (area of cross section) dx or dy depending on orientation
L = ∫ab √{1 + (f'(x))²} dx
Express a rational function as a sum of simpler fractions to facilitate integration.
Use ratio or root test to find radius; interval includes all x where series converges.
