If (\sin \theta=\cos \theta) and (0<\theta<\frac{\pi}{2}), what is the value of (\theta)?यदि (\sin \theta=\cos \theta) और (0<\theta<\frac{\pi}{2}), तो (\theta) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{\pi}{4})(\frac{\pi}{4})
From ( \sin \theta=\cos \theta), ( \tan \theta=1), and in the first quadrant ( \theta=\frac{\pi}{4}). In exams divide by ( \cos \theta) only when it is nonzero.(\sin \theta=\cos \theta) से (\tan \theta=1) और प्रथम चतुर्थांश में (\theta=\frac{\pi}{4}) है। परीक्षा में दोनों तरफ (\cos \theta) से भाग तभी दें जब वह शून्य न हो।
