which is equivalent to a single "implicit" equation: y(x+h) - y(x) = h * F(x+h, y(x+h)) It is called "implicit" because here the target y(x+h) is also a part of F. And note that quite similar equation is mentioned in the Modifications and extensions section of the wiki article. So now going to your case that equation becomes

Explicit vs. Implicit Both "explicit" and "implicit" are adjectives, commonly used in English, both in two different contexts. "Explicit" refers to something very exact, very clearly explained in the first place. Secondly, "explicit" can also be used when referring to a very detailed sexual or violent scene, usually in a movie or in a book.

• So far, we have seen explicit Euler –X(t+h) = X(t) + h X’(t) • Implicit Euler uses the derivative at the destination! –X(t+h) = X(t) + h X’(t+h) –It is implicit because we do not have X’(t+h), it depends on where we go (HUH?) –aka backward Euler 23 . Implicit Integration

The former means that you in general must solve a (non-linear) equation at each time step to obtain y n + 1. The typical way to do this to to use a non-linear equation solver such as Newton's method.
