Differentiate the function with respect to x in exercise 1 to 5

Q1. cos x cos 2x cos 3x

Ans. The given function is cos x cos 2x cos 3x

Let y = cos x cos 2x cos 3x

Taking logarithms both sides

log y = log (cos x cos 2x cos 3x)

log y = log cos x + log cos 2x + log cos 3x

Differentiating both sides

Ans.

Taking logarithms on both sides

Differentiating the given function with respect to x

Ans.The given function isย  ย  ย 

Taking logarithms on both sides

Differentiating the function with respect to x

Ans.ย 

Let ย  ย  ย  ย  ย 

Now,

Taking logarithms both sides

log u = x log x

Differentiating the function with respect to x

Now,

Taking logarithms both sides

log v = sin x log 2

Differentiating both sides with respect to x

Substituting the value of du/dx and dv/dx in the following equation

Q5.(x +3)2(x +4)3(x +5)4

Ans. The given function is (x +3)2(x +4)3(x +5)4

Let y = (x +3)2(x +4)3(x +5)4

Taking logrithms both sides

log y = log [(x +3)2(x +4)3(x +5)4]

log yย  = log(x +3)2+log(x +4)3+log(x +5)4

log yย  =2 log(x +3)+3log(x +4)+4log(x +5)

Differentiating both sides
