## Main Question or Discussion Point

I have learned that (cos x)

How come we don't write (ln x)

I just think it seems smarter when its written with as few symbols as possible.

(Or perhaps its just my textbook which don't write it this way?)

Thanks in advance!

^{a}can be written as cos^{a}x. And like wise for sin x and tan x.How come we don't write (ln x)

^{a}as ln^{a}x or (log x)^{a}as log^{a}x?I just think it seems smarter when its written with as few symbols as possible.

(Or perhaps its just my textbook which don't write it this way?)

Thanks in advance!
