Dec 03, 2018 · y = y0 +f (t0,y0)(t −t0) y = y 0 + f ( t 0, y 0) ( t − t 0) Take a look at the figure below. If t1 t 1 is close enough to t0 t 0 then the point y1 y 1 on the tangent line should be fairly close to the actual value of the solution at t1 t 1, or y(t1) y ( t 1). Finding y1 y 1 is easy enough.

Consider the problem of calculating the shape of an unknown curve which starts at a given point and satisfies a given differential equation. Here, a differential equation can be thought of as a formula by which the slope of the tangent line to the curve can be computed at any point on the curve, once the position of that point has been calculated. The idea is that while the curve is initially unknown, its starting point, which we denote by is kno…
