Re: this variable is undefined

You've not learned that all of the constraints have to come after the "given" statement?  Where is "Find"?

Go read the help files about how to set up a solve block!

 

Or are you just dumping on this forum?

thank you

 

but why d.a d.b is not corret it should be 0.1 and 0.1

Re: this variable is undefined

If ALL of your used variables have to be constant (even q=100) and you only want to vary d1 and d2m then you are asking for the impossible. There is a linear relationship between d1 and d2 and to fulfill your equation at least one of the two must be negative. So they can't be both in the range from 0 to 0.3.
