I want to know how to use the RMFI software to compute it! please show me all the steps of using software plz!!!

The steps of using software plz!!! DerivaGem calculator

= = 1. Using the RMFI software to compute Deltas of a put option with K = $50, r = 0.05,0 = 0.25, T = 1 year, when the underlying stock price is S = $25,$30, $35, $40, $45, $50,$55, T $60, $65, $70, $75, $80, respectively. Plot a graph of delta on the stock price series. Explain this graph - sign, monotonicity, and the curvature. = = 1.
