fx9700gh.jpg (28104 bytes)A more recent graphical calculator from Casio, the fx-9700GH offers more memory and a large display, but similar functionality to that found in earlier models, such as the fx-7700G.

The calculator's programming model is demonstrated by the following example, computing the logarithm of the Gamma function:

ln (2.506628283501+92.20704845211÷X-
    .2208497079533÷(X+3))+(X-.5)ln (X+3.85)-X-3.85->G
S<0=>ln (-π÷X÷sin πX)-G->G
