What is the value of (\cos \theta \cdot \sec \theta), when both are defined?(\cos \theta \cdot \sec \theta) का मान क्या है, जब दोनों परिभाषित हों?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (1)(1)
Since ( \sec \theta=\frac{1}{\cos \theta}), the product becomes (1). In exams identify reciprocal pairs quickly.(\sec \theta=\frac{1}{\cos \theta}) होने से गुणनफल (1) बनता है। परीक्षा में reciprocal pair तुरंत पहचानें।
