I am having troubles to make this formula to work anyone kwows why.

I am having troubles to make this formula to work anyone kwows why.

La componente es {=({a}*pow({c},2)+{b}*{a}+{c}*{b}) / (pow({c},2)+pow({a},2}+pow({b},2))}

La componente es {=({a}*pow({c},2)+{b}*{a}+{c}*{b}) / (pow({c},2)+pow({a},2 } +pow({b},2))}

You have } instead of ) in one place.

I did corrected that typo, such that the process goes to the final step in whish show the answers in this way.

So it replace the variables values, but do not make calculations.

This is something quite weird.

In the Edit the wildcards datasets page the calculations are not shown if there is a space in the equations although the values display correctly in preview.

So I will set a bug.

In the mean time remove the spaces in your equations.

This is something quite weird.

Or it may appears as.

Looking closely at the code, I notice (and remember ) that spaces was excluded from formulas inside {=...} in the question text and similarly in the multichoice answers.

This was done to limit possible interference if users use LATEX to show some maths equation which use the {...} in various ways, they could just put a space in their LATEX.

So I consider that this should be more a (undocumented) feature.

However if Tim wants this restriction to be removed, I will do it.

P.S. I added the {=...} feature in question text some years ago.
