How to Integrate a Constant Expression 3 dx

To integrate the constant expression 3 with respect to x, we will apply the basic rule of integration for constant functions.

The integral of a constant a with respect to x is given by the formula:

∫ a dx = ax + C

Here, C represents the constant of integration.

In our case, we are integrating the constant 3:

∫ 3 dx

Applying the formula:

• Let a = 3.
• This gives us: ∫ 3 dx = 3x + C

So the result of the integration is:

3x + C

In summary, when integrating a constant, we simply multiply the constant by the variable of integration and add the constant of integration.
