For $\sin α$ you must have ratio of side opposite of $α$ and chord total triangle angels is 180 and $\sin$ of 180 is 0 so i think $\sin 495$ be a negative number $\sin α = \frac{a}{c}$ ( side opposit of alpha / chord)

I am stuck with the simple expression

\frac{\cos^{2} (θ + α)}{1 - \cos^{2} (θ - α)} = const.

where

θ

is a variable and

α

is the number satisfying

α = \tan^{- 1} (\frac{4}{3})

Prove that

\tan^{- 1} \frac{\sqrt{1 + x^{2}} + \sqrt{1 - x^{2}}}{\sqrt{1 + x^{2}} - \sqrt{1 - x^{2}}} = \frac{π}{4} + \frac{1}{2} \cos^{- 1} x^{2}

?
Let the above expression be equal to

ϕ

\frac{\tan ϕ + 1}{\tan ϕ - 1} = \sqrt{\frac{1 + x^{2}}{1 - x^{2}}}

\frac{1 + \tan^{2} ϕ + 2 \tan ϕ}{1 + \tan^{2} ϕ - 2 \tan ϕ} = \frac{1 + x^{2}}{1 - x^{2}}

\frac{1 + \tan^{2} ϕ}{2 \tan ϕ} = \frac{1}{x^{2}}

\sin 2 ϕ = x^{2}

ϕ = \frac{π}{4} - \frac{1}{2} \cos^{- 1} x^{2}

prove that maximum value of

\cos α \cos β

occurs when

α = β = \frac{σ}{2}

If

α, β \in (0, \frac{π}{2})

and

α + β = σ

(constant), then prove that maximum value of

\cos α \cos β

occurs when

α = β = \frac{σ}{2}
