JEE Mains · Maths · STD 12 - 7.2 definite integral
The value of the integral \(\int_{0}^{\pi}|\sin 2 x| dx\) is
- A \(1\)
- B \(2\)
- C \(3\)
- D \(4\)
Answer & Solution
Correct Answer
(B) \(2\)
Step-by-step Solution
Detailed explanation
Put \(2 x=t \Rightarrow 2 d x=d t\) \(\Rightarrow I=\frac{1}{2} \int_{0}^{2 \pi}|\sin t| d t\) \(=\int_{0}^{\pi}|\sin t| d t\) \(=2\)
