Maharashtra CET 2016: If Rolle's theorem for f(x)= ex (sinx - cosx) is verified on [π/4, 5 π/4], then the value of c is (A) π/3 (B) π/2 (C) ... Given that y = c1ex cosx + c2ex sinx is the general solution of a second- order differential equation with the following boundary-value conditions: y(0) = a ... tanx = sinx/cosx. This identity can easily be shown by asking the student to draw a right-angled triangle, with one of the remaing two angles labelled x. cos(x + h) = lim h→0.
