arccosh(θ)=0.86806

Solution

arccosh (θ) = 0.86806

Solution

No Solution for θ \in R

Solution steps

arccosh (θ) = 0.86806

Subtract

0.86806

from both sides

arccosh (θ) - 0.86806 = 0

Solve by substitution

arccosh (θ) - 0.86806 = 0

Let:

arccosh (θ) = u

u - 0.86806 = 0

u - 0.86806 = 0 : u = 0.86806

u - 0.86806 = 0

Move

0.86806

to the right side

u - 0.86806 = 0

Add

0.86806

to both sides

u - 0.86806 + 0.86806 = 0 + 0.86806

Simplify

u = 0.86806

u = 0.86806

Substitute back

u = arccosh (θ)

arccosh (θ) = 0.86806

arccosh (θ) = 0.86806

Rewrite using trig identities

- 0.86806 + arccosh (θ)

Use the Hyperbolic identity:

arccosh (x) = ln (x + x^{2} - 1)

= - 0.86806 + ln (θ + θ^{2} - 1)

- 0.86806 + ln (- 1 + θ^{2} + θ) = 0

Move

0.86806

to the right side

- 0.86806 + ln (- 1 + θ^{2} + θ) = 0

Add

0.86806

to both sides

- 0.86806 + ln (- 1 + θ^{2} + θ) + 0.86806 = 0 + 0.86806

Simplify

ln (- 1 + θ^{2} + θ) = 0.86806

ln (- 1 + θ^{2} + θ) = 0.86806

Apply trig inverse properties

ln (- 1 + θ^{2} + θ) = 0.86806
