Loops to Find Maximum Value

[ppal]

Find the maximum value from a list of data and  also the value that results in the maximum data.

I have attached a mathcad prime 5 file and pic if you dont have Prime 5

Its not clear to me what values you look at to find the maximum.

Are you looking for the maximum of the 11 values which are calculated by

25*sin(j) * 15*sin(j) * ... * 20*sin(j)

as you write about the max value of the "product" (which?).

Or are you looking at the max of the 88 different values calculated by

25*sin(j)

15*sin(j)

...

In both cases it would suffice to look for the max of the eleven sin(j)  values and you get the max always for j=1

You may use jmax:=lookup(max(sin(j)), sin(j), j)[0 to find out that jmax=1.

Hi

I am after the max of 88 values.

The function may not be sine it could just be an list of numbers

So here is one way to get what you are looking for:

File in Format Prime 5 attached.

Here is a different approach using a used defined utility function

Here's a compact implementation that also works in Prime Express:

Prime 4 file is attached.

Success!
