URGENT HELP with using Casio fx-83GT PLUS for Miller-Orr Cash question for F9

NNeville9y ago

John I’m also having problem with entering the formula into my calculator, I have a Casio fx-83GT PLUS I have my exam coming up on Wednesday and it would be really helpful to know which buttons to hit and in which order! I’m doing a different question, where the details are as follows: Transaction cost is $30 Variance of cash flow is $270,000 Daily interest rate is 0.025% I think it’s just the 1/3 that’s throwing things out, not sure which button to press! The spread should come out to $8,689 I hope you can help John Regards Neville

I am sorry, but different calculators need the buttons pressed in different ways, and I don't have your calculator!!! I can only suggest that either you check the manual (if you have lost it then you can find a copy online by searching on Google), or else ask in the other F9 forum and other students with the same calculator may be able to help you. For the 1/3 in the spread formula, it means you take the cubed root. You should have either a cubed root button or else a button marked "y root x" (it is difficult to type what it looks like!)
