Newbie problem - Using a range of angles inside a cosine function - Trying to use cos(variable angle) - Messages
#1 Posted: 10/3/2012 6:41:00 AM
Hi,
I'm trying to convert some old Mathcad files into SMath but am stuck with what must be an elementary problem, I've looked at various tutorials but can't find a solution, no doubt due to my own incompetence.
I am defining the following variables: angle:=72 and varangle:= 0, angle/2..360
In Mathcad if I then define: test(varangle):= cos(varangle) the output of test(varangle) displays correctly in a column.
If I try the same in SMath I receive either an 'argument must be scalar' or 'fill in all empty elements' error.
Thanks for any advice.
Screenshots of Mathcad and SMath attached.
btw, great software.

Correct me if i'm wrong, trigonometric functions don't support arrays currently.
For now, you can do something like this.

You can convert the vector into a system (by w3b5urf3r_reloaded)

did arrays appear in trigonometric functions?

An alternative to the vectorize() function is the use of index vectors.
They, however, only work if they are used in a definition.
