y= f(a)+ f'(a)(x−a)
differential form
dy = f’(x) dx
Newton’s method
xₙ₊₁ = xₙ - (f(xₙ) / f’(xₙ))
A separable differential equation is any equation that can be written in the form
y'=f(x)g(y) or y’ = f(x)/ g(y)
Newton’s law of cooling (1)
dT/dt = k(T-Ts)
Newton’s law of cooling (2)
T(t) = (To - Ts)e^kt + Ts
