What is (\sec(\frac{\pi}{2}-x)) equal to?(\sec(\frac{\pi}{2}-x)) किसके बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\cosec x)(\cosec x)
(\cos(\frac{\pi}{2}-x)=\sin x), so (\sec(\frac{\pi}{2}-x)=\frac{1}{\sin x}=\cosec x). Complementary angles give cofunctions.(\cos(\frac{\pi}{2}-x)=\sin x), इसलिए (\sec(\frac{\pi}{2}-x)=\frac{1}{\sin x}=\cosec x)। पूरक कोण में सहफलन बनता है।
