If (x) is in the second quadrant and (\cos x=-\frac{3}{5}), what is the value of (\tan x)?यदि (x) दूसरे चतुर्थांश में है और (\cos x=-\frac{3}{5}), तो (\tan x) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: -(\frac{4}{3}) / (-\frac{4}{3})-(\frac{4}{3}) / (-\frac{4}{3})
In the second quadrant, (\sin x) is positive and (\cos x) is negative. Since (\sin x=\frac{4}{5}), (\tan x=-\frac{4}{3}).दूसरे चतुर्थांश में (\sin x) धनात्मक और (\cos x) ऋणात्मक होता है। (\sin x=\frac{4}{5}), इसलिए (\tan x=-\frac{4}{3}) है।
