In older maple versions, calculating your monthly payments on a car, for example, have become a little more cumbersome.
Older versions had a built in function called finance, which has since been removed in the newer versions. The syntax for the command was finance(amount= , interest=, payments=, or periods=) you could leave out one and maple would calculate the unknown. The most common unknown was the amount of your monthly payments on a car which nowadays is usually a fixed finance level of 48 months.
The older maple syntax was
finance(amount=21000,interest=.019/12,periods=48); with the answer coming out as payment=454.68
Now in the new maple since no such command exists. You have to know the equation, and this is where a helpful reference of equations on a help page would come in handy. However for the time being we must look elsewhere and we find the equation to be M:=(P*r*(1+r)^n)/(((1+r)^n)-1); with A-amount, n-periods, r-interest rate and M being the monthly payments.
Does anyone know why maple removed the finance command? Is there a similar command in the newer versions of Maple that I'm missing?
Can I make a finance command?
