AP EAMCET · Maths · Area Under Curves
The area of the region (in sq. units) enclosed between the curves \(y=|x|, y=[x]\) and the ordinates \(x=-1, x=0, x=1\) is
- A 2
- B \(\frac{3}{2}\)
- C 3
- D \(\frac{5}{2}\)
Answer & Solution
Correct Answer
(A) 2
Step-by-step Solution
Detailed explanation
\(A = \int_{-1}^{0} (-x - (-1)) dx + \int_{0}^{1} (x - 0) dx\) \(A = \left[ -\frac{x^2}{2} + x \right]_{-1}^{0} + \left[ \frac{x^2}{2} \right]_{0}^{1}\) \(A = \left(-\frac{0^2}{2} + 0\right) - \left(-\frac{(-1)^2}{2} + (-1)\right) + \left(\frac{1^2}{2} - \frac{0^2}{2}\right)\)…
