How to Find the Integral of sec(x)dx Using Substitution

sec(x)dx

To find the integral of sec(x)dx, you can use the technique of substitution

To find the integral of sec(x)dx, you can use the technique of substitution. Let’s take a step-by-step approach:

Step 1: Identify a suitable substitution:
We know that the derivative of sec(x) is sec(x)tan(x). So let’s choose u = sec(x) and du = sec(x)tan(x)dx.

Step 2: Rewrite the integral using the substitution:
Using the substitution u = sec(x), we can rewrite the integral as ∫du.

Step 3: Solve the integral:
Now, we can solve the integral of du, which is simply u + C, where C is the constant of integration.

Step 4: Final substitution:
Using the substitution u = sec(x), we can replace u to get the final answer:
∫ du = sec(x) + C.

Therefore, the integral of sec(x)dx is sec(x) + C, where C is the constant of integration.
