Integrating factor

Summary

An integrating factor is a function by which one multiplies a differential equation so that it can be integrated directly. For the linear equation y′+py=qy' + p y = q, the factor e∫pe^{\int p} turns the left side into the derivative (e∫py)′\left(e^{\int p} y\right)'. See the definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
