ln(cosh(0))

Solution

ln (cosh (0))

Solution

0

Solution steps

ln (cosh (0))

Rewrite using trig identities:

cosh (0) = 1

cosh (0)

Use the Hyperbolic identity:

cosh (x) = \frac{e ^{x} + e ^{- x}}{2}

= \frac{e ^{0} + e ^{- 0}}{2}

Simplify

= 1

= ln (1)

Simplify

ln (1) : 0

ln (1)

Apply log rule:

lo g_{a} (1) = 0

= 0

= 0
