hi all, i am having trouble calculating the learning curve formula y = Ax b i use a sharp calculator model el-w531.. i would be very grateful for any help. say for example y = 30 * 3 -0.201 The answer is y = 24.06 But how do you calculate this on a calculator? on open tuition video lecture it mentions xy and +/- buttons but these are not on my calculator.
I also have a casio fx-85ES but can’t seem to work it out on this either. Perhaps I have the wrong mode set on them??Any help is much appreciated. Thanks, Michael.
Hi Michael
I looked up the manual for your calculator, and it seems that (for your example) you need to enter the following (it is going to look silly because I cannot type certain symbols on here, but I hope it makes sense!!)
3
then the key that has y to the power x on it
then the key ‘(-)’ (the key has the minus sign in brackets)
then 0.201if you hit ‘=’ then this should give you 0.80186
you can then multiply by 30 and you will get 24.06
(Maybe you can type ’30’ and ‘x’ and then what I wrote above – I am not sure!)
I cannot check it myself because my calculator uses a different logic.
Let me know if this works or not!

In calculating the learning curve, I understand calcuating the log section. Having problem arriving at the unit cost using the equation.
The equation gives you the average cost per unit for any number of units.
So, for example, if you wanted to know the total time for 30 unites then you calculate the ave time per unit using the formula and then multiply by 30.
If you want to know how long the 30th unit will take then you do the same as above using 29 instead of 30. This will give tou the total time for 29. Then if you tract the total for 29 from the total for 30 you will have the time for the 30th.
To get the cost you multiply the time by the cost per hour.
