HP35s Speed of integration
I made a test using the integration example from HP35s Training Aids, with the equation 1/(1-COS(X)+0.25), from 0 to 2π.

In the first case the equation was written as an RPN program and the execution time was about 6s.

In the second case the equation was also an RPN program with just one line EQN 1/(1-COS(X)+0.25) and the execution time was 8s.

In the third case it was an equation in equation list, and it took only 3s.

In the 2nd case it seems that in every iteration the calculator translates again the EQN.
In the 3rd case it seems that it translates it the first time to some internal very fast representation and do the math much quicker.
