## ∫cos u du

### To find the integral of the function ∫cos(u)du, we can follow these steps:

Step 1: Identify the integration variable

To find the integral of the function ∫cos(u)du, we can follow these steps:

Step 1: Identify the integration variable.

In this case, the integration variable is u.

Step 2: Recall the trigonometric identity.

Recall the trigonometric identity for the cos(u) function:

∫cos(u)du = sin(u) + C

where C represents the constant of integration.

Step 3: Apply the trigonometric identity to the function.

Using the trigonometric identity, we can rewrite the integral as:

∫cos(u)du = sin(u) + C

Step 4: Simplify the expression.

Since we have already applied the trigonometric identity, we don’t need to simplify the expression any further.

Step 5: Final answer.

Therefore, the integral of cos(u) with respect to u is:

∫cos(u)du = sin(u) + C

where C represents the constant of integration.
