Q). Differentiate:
y = tan x sin x

Dear Student ,
 
Please find below the solution to the asked query :

y=  tan xsin xTaking log on both sides, we getlog y = log  tan xsin xlog y = sin x log tan xDifferentiating both sides wrt x, we get1y dydx = cos x log tan x + sin x 1tan x . sec2xdydx= y cos x log tan x + sin x cos xsin x . sec2x =  tan xsin x cos x log tan x + sec x        ANS...
