At which (x) does (y=\cos x) have its minimum on (0\le x\le2\pi)?फलन (y=\cos x) का (0\le x\le2\pi) में न्यूनतम मान किस (x) पर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x=\pi)(x=\pi)
The minimum of (\cos x) is (-1), which occurs at (x=\pi). When reading graphs, identify maximum and minimum points separately.(\cos x) का न्यूनतम मान (-1) होता है, जो (x=\pi) पर है। ग्राफ पढ़ते समय अधिकतम और न्यूनतम बिंदु अलग पहचानें।
