Getting error 'This value must be scalar'

Hi

Attached is a calc Im working on. Everything seems OK until I try to enter a value for epsilon/D and then the program keeps popping that it must be a scalar value. Progressively I wish to use the value of Epsilon/D and then calculate Cf. Here also the program keeps saying Cf is not defined. Kindly assist.

The reason for the error message is that you have typed square brackets and thus had created 1x1 matrices.

Use normal parentheses throughout!

Not sure what you mean with your second question. Do you want to define a function for C.f dependent on epsilon?

Or are you trying something like this:

Werner,

THank you for your reply. Its very helpful. One question. You have used the solve feature. How do you activate this. I don't see it on the GUI of Prime 4. Whats the meaning of float,6. Why 6? Please enlighten me.

Regards

Shastry.

Hi

Further to my previous query, I eventually wish to write out an equation for Cf which is dependant on epsilon/D and as epsilon/D keeps varying the program should automatically calculate Cf. How can I achieve this.
