1. ## Calculus 4: P=f(t,c)

Hello everyone,

Could someone please tell me if this is correct?

P=f(t,c)

Evaluate ft and fc.

My attempt:

ft(t,c)-->ft(18,6)=

fc=(c,t)-->fc(18,6)=

Thank you very much

2. What do you mean by ft and fc, do you mean:

$f_t$ and $f_c$ as in, partial derivatives, or do you mean:

$ft$ and $fc$ for something else?

3. Sorry, I mean and as in, partial derivatives.

Could you please tell me if what I said was correct?

Thank you

4. More questions:

What is the function P, is there any equation or anything?

And why does $f_t(t,c) \rightarrow f_t(18,6)$

There's really no way to verify what you have... There's nothing to compare your answer to...
