Q2) i. Using properties for Logarithmic function, Only Simplify without differentiation the following expression for y: 3/4 y = In etan"!x (In x)8x (sec x3)3 Vx8 + 1 ii. Find y' for the following implicit functions: (a) y = y sin x + y2 + x8. (b)(1 + cos-1 x)sin y = y3 + (x) sinh x. If x = tanh-1 t and y = (1 - t2)2, Find y". If x= cos 2t and y = sin22t, show that iv. -2. dx?
