If (\cos \theta=0), what is the general solution for (\theta)?यदि (\cos \theta=0), तो (\theta) का सामान्य हल क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\theta=\frac{(2n+1)\pi}{2})(\theta=\frac{(2n+1)\pi}{2})
( \cos \theta) is zero at odd multiples of ( \frac{\pi}{2}). In exams remember the pattern ( \frac{(2n+1)\pi}{2}).(\cos \theta) शून्य odd multiples of (\frac{\pi}{2}) पर होता है। परीक्षा में (\frac{(2n+1)\pi}{2}) पैटर्न याद रखें।
