Im looking for a proof of the derivative of the trig functions... FROM WHICH I can derive cosh x = [ e^x + e^-x ] / 2

Can anyone help with this?

The hyperbolic functions existed independent from the normal trig functions, and prior to complex analysis and their subsequently proven relationship.

Im looking for a way to prove:
cos ix = [ e^i(ix) + e^-i(ix) ] / 2 = [ e^x + e^-x ] / 2 = cosh x

... without merely defining cosh x = [ e^x + e^-x ] / 2.

My point is that how do we know cosh x = [ e^x + e^-x ] / 2 ?

cos ix = [ e^x + e^-x ] / 2... but how does that happen to be cosh also?

How do you calculate the area of a trapezoid if the units are in fractions?
Base #1: 3/4 (thats a fraction... 3 over 4)
Base #2: 1/4 (also a fraction... 1 over 4.)
Height: 1

How would you calculate the area of this trapezoid?

A 0.250-kg coffee cup at 20 degrees C is filled with 0.250 kg of boiling coffee. The cup and the coffee come to thermal equilibrium at 80 degrees C. If no heat is lost the environment, what is the specific heat of the cup material? [Hint: Consider the coffee essentially to be boiling water.]

Having trouble getting my head around this one, don't really understand what "compounded continuously" means:

Find the value at the end of 20 years of an investment of $100 which earns interest at the rate of 5% compounded continuously
