(30b) Lambert w Programme for Solve
To find Lambert w function value for X, store Xvalue in memory 2, enter the programme listed below, exit programme, hold down shift
key & press & release ÷ & release shift key, see the prompt “SOLVE” & enter 1 & before you can say “Hey presto” the value of w is displayed. Solve for memory 1 given memory 2 value returns w in the equation X = w * e^w Similarly, solving for memory 2 given memory 1 value returns the antiLambert w value, ie X in the above equation. 0 P6 1 RCL 1 2 Input 3 e^X 4 * 5 RCL2 6 RTN
