Largest number

In Mathcad If I have 3 functions a, b and c and I whant d to be the biggest out of the three how do I do that? Like:

d=max[a:b:c]=biggest value

Thanks for help

That will ONLY work if a, b and c are __values__ (or sets of values such as array or matrices): you'll get the largest of any of the values and/or array- and/or matrix-elements.

If a, b and c are really functions, you'll need a litte more.

Success!

May be so

a(x):=…

**b(x):=…**

**c(x):=…**

**d(x):=max(a(x), b(x), d(x))**

And what Valery shows (above, Thanks Valery!) is one possibility of 'a little more'.

Essentially what goes on there is that a(x), b(x) etc are numbers, each corresponding to a call to the d(x) function.
