1. Another method of substitution cipher is based on a keyword.
2. There was developed the method of substitutions of problem solving on the graphs.
3. If we are interested in finding antiderivative of an arbitrary function by method of substitution then there is no general method to find the substitution function . When the mathematician or the instructor chooses a substitution function he generally does not give the reason for making the particular substitution . He does not divulge how he arrived at the particular idiosyncratic substitution or what thought led him to a unique substitution . Is this done by a heuristic choice from a set of infinite possible substitution functions . But heuristic approach does not guarantee to make the process of finding antiderivative simple . One may end up in a mess if he fails to find the particular unique substitution function . Thus I find the application of method of substitution a very unscientific grey area . Ican give an example to illustrate my point . Take for example Integral dx / { ( p * x + q ) Sqrt ( a * x ^ 2 + b * x + c ) } . As far as I know this indefinite integral can be simplified by the substitution ( p * x + q ) = 1 / z . But my question is how will one arrive at this substitution if he has no apriori hint.
