Solution: Let B = A + H. Then tan(α) = A x and tan(β) = B x so α = arctan( A/x ) and β = arctan( B/x ). The viewing angle is θ = β – α = arctan( B/x ) – arctan( A/x ). We can maximize θ by calculating the derivative dθ dx and finding where the derivative is zero. Since θ = arctan( B/x ) – arctan( A/x ) , dθ
Arctan Calculator. In mathematics, the inverse trigonometric functions are the inverse functions of the trigonometric functions. Specifically, the arctan is the inverse of the tangent. It is normally represented by arctan(θ) or tan-1 (θ).
This tip shows how to add an equation with trigonometric functions, for example, the Euler's formula. How to add an equation in your document, see Working with Microsoft Equation.
