## How can I DO?

I want to appy cl1~cl8 ,cd1~cd5 equations to g1, g2 equation whenever aoa is variable.

these equations about cl, cd got by using excel program range from aoa.

For example, If I got aoa=-35, I want to appy it to cl1 equation.

if I got aoa= -15, I want to appy it to cl2 equation.

Could you help me?

## Re: How can I DO?

You define functions cl1 thru cl8, then g1 calls for function cl. YOU NEVER DEFINED cl !!!! So you got a red box around that in the expression for g1.

Think that might be a clue? That might be where the trouble is?

cl1 is not cl. cl2 is not cl. cl3 is not cl.

And you still haven't fixed the angle phi, you just keep going, posting the same problems over.

There have been some smart people here (not me) trying to help you; but you keep making the same beginner mistakes.

Start fixing what's been pointed out, start reading the help files on how things work.

you said that I still haven't fixed the angle phi.

I am sorry to ask you again. But I can't understand well why it has problem.

And I also saw help manual to solve my problem. But it is not sufficient to solve my problem.

## Re: How can I DO?

Could you explain for me again?

I am sorry to bother you becasue I am not good at english.

You are not closing out any of the threads you have created and carrying issues from thread to thread.

The best place to learn in my opinion in on this forum. The search feature works well if you know what you are looking for.

## Re: How can I DO?

okay I know this site is good for me. But it is too many material to study in short time.

Is it possible to know which section do I need to study?

If I have sufficient time, I am surely to study all section in this site.

But I don't have many time unfortunely.

Unfortunately I cannot tell you that, you have to identify where you are struggling. Werner has suggested various subjects many times, I would suggest following up on that may be a good start.

When I was learning I concentrated on the problem in hand. If it is a solve / block program, concentrate on that. Do not jump to something else as you will struggle to take it all in.
