Given that x 2 + 2 x y s e c θ + y 2 = 0. Comparing this equation with the general equation a x 2 + 2 h x y + b y 2 = 0, We get. a = 1, b = 1 and. 2 h = 2 s e c θ. ⇒ h = s e c θ. We know the angle between the two lines given by.
WebThis is a standard problem for variation of parameters. y''+y = 0 has the solution y=c_1 cos(x) + c_2 sin(x) Let: Y = u(x)cos(x)+v(x)sin(x) Y' = u'cos(x)+v'sin(x)-usin(x)+vcos(x) We have ... Prove that \sec^2{\theta}=(4xy)/(x+y)^2 only when x=y Web1 Aug 2024 · Solution 1. We have sec 2 θ ≥ 1 for all θ at which sec θ is defined. So it is enough to show that 4 x y ( x + y) 2 ≤ 1, with equality only when x = y. To show that 4 x y ( x + y) 2 ≤ 1, we show equivalently that ( x …
