What is the area between y=x² and the x-axis from x=-1 to x=1?
y=x² और x-axis के बीच x=-1 से x=1 तक area क्या है?
Show answer and explanation
Correct Answer
B. 2 / 3
ExplanationStep 1: Identify even function area. Step 2: x² is even, so area=2∫₀¹x²dx=2/3. Step 3: Exam tip: For even functions on symmetric limits, double the integral from 0 to a.
Step 1: अवधारणा even function area है। Step 2: x² even है, इसलिए area=2∫₀¹x²dx=2/3। Step 3: Exam note: symmetric limits में even function के लिए double करें।
