Given that x = ln(sec(2y)) find dy/dx

x = ln (sec (2y)) The chain rule states that d/dy f (g (y)) = f'(g(y)). g'(y) Here g(y) = sec(2y) so g'(y) = 2.sec(2y).tan(2y) And f(y) = ln (y) so f'(y) = 1 / y Thus dx/dy = (1 / sec(2y)) . (2.sec(2y).tan(2...

Solve the equation x^2 - 8x + 5 = 0 by completing the square

x 2 - 8x + 5 = 0 => (x 2 - 8x + 16) - 11 = 0 =>(x - 4) 2 = 11 =>x - 4 = +- sqrt(11) =>x = 4 +- sqrt(11)
