If (\sin x=\frac{3}{5}) and (x) lies in the first quadrant, what is the value of (\tan x)?यदि (\sin x=\frac{3}{5}) और (x) प्रथम चतुर्थांश में है, तो (\tan x) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \frac{3}{4} )( \frac{3}{4} )
We get (\cos x=\frac{4}{5}), so (\tan x=\frac{\sin x}{\cos x}=\frac{3}{4}). In exams, decide the sign from the quadrant.(\cos x=\frac{4}{5}) होगा, इसलिए (\tan x=\frac{\sin x}{\cos x}=\frac{3}{4})। परीक्षा में चतुर्थांश से चिन्ह तय करें।
