# Newbie Question; what am I missing here?

## Newbie Question; what am I missing here?

(OP)

Vin:=5.0
Vout:=3.3

D:=.5  a guess

Given
Vout = Vin.D    (the dot here is realy a multiply)

D:=Find(D)

D=             (there is a place holder after the =)

My question is: Why doesn't D=0.66???

### RE: Newbie Question; what am I missing here?

The "equation(s)" after the given must be entered using [ctrl]+=, i.e., a control-enter, which normally appears as a bolded equal sign.

I did that for the equation Vout = D*Vin

Still doesn't work     try it

### RE: Newbie Question; what am I missing here?

works perfectly for me.

There must be something wrong with your typing, the error message should not be a placeholder.

did you type D=, not D:

Thanks Greg!

That was it,  I had typed Cntl+= for that last =

Interesting  there are are at least three versions of "=" then:

type: =
type: :
type: cntl + =  (control =)

### RE: Newbie Question; what am I missing here?

This is all explained in the manual as well as the help files.

:=               is the assignment operator
=                is the result operator
[crtl]=          is the constraint operator
