EXERCISE 30.4 PAGE NO: 30.39

Differentiate the following functions with respect to x:

1. x3 sin x

Solution:

Let us consider y = x3 sin x

We need to find dy/dx

We know that y is a product of two functions, say u and v, where,

u = x3 and v = sin x

∴ y = uv

Now let us apply the product rule of differentiation.

By using the product rule, we get

2. x3 ex

Solution:

Let us consider y = x3 ex

We need to find dy/dx

We know that y is a product of two functions, say u and v, where,

u = x3 and v = ex

∴ y = uv

Now let us apply the product rule of differentiation.

By using the product rule, we get

3. x2 ex log x

Solution:

Let us consider y = x2 ex log x

We need to find dy/dx

We know that y is a product of two functions, say u and v, where,

u = x2 and v = ex

∴ y = uv

Now let us apply the product rule of differentiation.

By using the product rule, we get

4. xn tan x

Solution:

Let us consider y = xn tan x

We need to find dy/dx

We know that y is a product of two functions, say u and v, where,

u = xn and v = tan x

∴ y = uv

Now let us apply the product rule of differentiation.

By using the product rule, we get

5. xn loga x

Solution:

Let us consider y = xn loga x

We need to find dy/dx

We know that y is a product of two functions, say u and v, where,

u = xn and v = loga x

∴ y = uv

Now let us apply the product rule of differentiation.

By using the product rule, we get
