फलन \(y=\cos x\) का \(0\le x\le2\pi\) में न्यूनतम मान किस (x) पर है?
At which (x) does \(y=\cos x\) have its minimum on \(0\le x\le2\pi\)?
Explanation opens after your attempt
Correct Answer
A. \(x=\pi\)
Concept
The minimum of \(\cos x\) is (-1), which occurs at \(x=\pi\). When reading graphs, identify maximum and minimum points separately.
Why this answer is correct
The correct answer is A. \(x=\pi\). The minimum of \(\cos x\) is (-1), which occurs at \(x=\pi\). When reading graphs, identify maximum and minimum points separately.
Exam Tip
\(\cos x\) का न्यूनतम मान (-1) होता है, जो \(x=\pi\) पर है। ग्राफ पढ़ते समय अधिकतम और न्यूनतम बिंदु अलग पहचानें।
