I remember in Pre-Calculus, my teacher told us to make sure we were using capital or lowercase letters in our trig identities correctly. There was a difference between:
cos(Θ)=a/h
and
Cos(Θ)=a/h
I don't remember what the difference in solving the problem was.
I would appreciate your help!

It is of no difference between capital or lowercase letters in trigonometric functions. The cos(x), sin(x), and tan(x) are "symbols" use to represent the functions (like the multiplication is a "symbol" to represent long additions).

When solving Trig identities, you only use lowercase letters for the 6 trig functions:
sinx, cosx, tanx and their multiplicative inverses functions… instead of
SINx, COSx… no, no.

Some people say that
Cos(Θ)=a/h
only refers to the primary value of Θ for cosine on the interval [0,π].
whereas
cos(Θ)=a/h
refers to all solutions for Θ.
Not everyone agrees with this distinction however.

Maybe he was referring to the names of the angles and sides, as that would certainly be important -- the angles being A, B, C and the sides being a, b, c.

Only if you're using MAPLE software. It thinks there's a difference between Cos and cos. So, really, NO, there is no difference.

No difference - just personal style.
