Example 32 Differentiate sin , > 0 . . . . Let y = sin Taking log both sides log = log sin log = sin . log Differentiating . . . ( log ) = sin log ( log ) = ( sin ) .log +sin . ( log ) ( log ) = cos log + sin 1 1 = cos log + sin 1 = cos x log + 1 sin Putting back = = cos log + 1 sin = cos log + 1 = cos log + 1 sin = cos log + 1 sin = . + .
