Q: What is the integral of cos(2x) dx? (2021)
Solution:
The integral of cos(2x) is (1/2)sin(2x) + C.
Steps: 5
Show Steps
Step 1: Identify the function to integrate, which is cos(2x).
Step 2: Recall the integral formula for cos(kx), which is (1/k)sin(kx) + C, where k is a constant.
Step 3: In our case, k is 2 because we have cos(2x).
Step 4: Apply the formula: The integral of cos(2x) is (1/2)sin(2x) + C.
Step 5: Write down the final answer: (1/2)sin(2x) + C.
