To prove the identity (sinθ−secθ)2+(cosθ−cscθ)2=(1−secθcscθ)2, we will start by simplifying the left-hand side (LHS) and show that it equals the right-hand side (RHS). Step 1: Expand the LHSWe start with the left-hand side:(sinθ−secθ)2+(cosθ−cscθ)...
As in ordinary trigonometric function, we know that the coordinates of points on the unit circle are (cos θ, sin θ), similarly in hyperbolic functions, (cosh θ, sinh θ) forms right half of equilateral hyperbola.These functions can be solutions of various linear differential equations, ...
