Ex 5.4, 2 (Method 1) Differentiate . . . x in , sin 1 Let = sin 1 Differentiating both sides . . . = sin 1 = sin 1 . sin 1 = sin 1 . 1 1 2 = Ex 5.4, 2 (Method 2) Differentiate . . . x in , sin 1 Let = sin 1 Let sin 1 = = Differentiating both sides . . . = We need in denominator, so multiplying & Dividing by . = = = = Putting value of = sin 1 sin 1 = sin 1 1 1 2 =
