taylors polynomial

P(x) = f(a) + f’(a)(x-a) + (f’’(a)(x-a)²)/2! …

16
New cards

newtons method

xn+1 = xn - f(xn)/f’(xn)

17
New cards

eulers method

xn = xn-1 + h

yn = yn-1 + hf(xn-1, yn-1)

initial condition is your starting point (xn, yn)

h = stepsize

approximating y(xf) xf = final xn

18
New cards

linear approx multivariable

f(x,y) = f(a,b) + df/dx(a,b)(x-a)+df/dy(a,b)(y-b)

19
New cards

critical points multivariable

D(x) = fxx*fyy - (fxy)²

D(x) > 0 fxx > 0 → local min

D(x) > 0 fxx < 0 → local max

D(x) = 0 → saddle point

20
New cards

(f○g)(x)

plugging in g(x) as x in f(x)

21
New cards

quadratic formula

b±√(b²-4ac))/(2a)
