# 关于参数数量与输入的问题

Not a Problem

I'm doing a linear simulation using geogebra. And the simlulation uses six parameters. But when I finished entering the formula, only five parameters was generated automatically. So could geogebra generate only five parameters, or there is someting wrong with my entering?

Please send a file so we can see what you exactly want. 'The simulation uses six parameters' and 'the formula' is not clear for someone who doesn't know what you exactly want to do.

The formula and the output in Geogebra are showed in the next graphs. And where I replace "t" with "d", then the sixth parameter can be found in the interface lying on the left.

Also check the syntax in your formulas. You need to enter a blank space or a product symbol * between a parameter and a variable, when they are multiplied.

So

a*x is correct, while ax doesn’t generate a slider for a, because GeoGebra reads it as a whole.

But, as Chris said, it’s impossible to help without your file. Mine was just meant as a general suggestion.

It is for sure that using * can solve most of the problems most of times. But unluckily this doesn't work at this time ; (

'At this time' is not helpful to give you a proper answer. You've been asked twice to prvide a file or at least a concrete case. We can't do more

But I HAVE given you two graphs in you reply. So maybe you've ignored what I have posted in your reply.

I'm sorry, I don't want to be rude and I didn't ignore anything, but you just added two pictures (no ggb file nor link to an uploaded file). The pictures only show two algebra views, one in an Asian alphabet most moderators cannot read. The second is in English. But in it I can only see one equation an some sliders that don't appear in the equation. Without a grahical nor any explication nobyy knows what you want.

So: send the file or upload it and send the link and explain what's the problem with this equation and what you want to draw.

I'm sorry. That's ok and I didn't mean to blame you. And this problem has been solved by substituding one parameter with another letter. Maybe you need to put a direction/discipline on the main page of the forum.

Best regards.

simply x,y,t are usually variables for function. a,b,q,h,r are generated like sliders by GG. use another letter for t
