Question

What does the equation sind(cosd(cosh(sinh(0)))) produce?

Answer 1

i will give medals

Answer 2

do you know what the sin of 0 is?

Answer 3

it's not an equation. If it is so, where is = sign?

Answer 4

i interpret it as he wants to simplify.
most people dont worry about math terminology like math people do.

Answer 5

Ok we know that sinh(0)=0 and cosh(0)=1
Basically
Hyperbolic sine : \( \sinh x = \large \frac{e^x - e^{-x}}{2}\)

Hyperbolic cosine:\( \cosh x = \large \frac{e^x +e^{-x}}{2}\)

Answer 6

So lets start off with the innermost function which is sinh(0)=0
Then we plug that into cosh(0)=1
hmmm Now I am stuck. I have never come across the term cosd
