यदि (x) दूसरे चतुर्थांश में है और \(\cos x=-\frac{3}{5}\), तो \(\tan x\) का मान क्या है?
If (x) is in the second quadrant and \(\cos x=-\frac{3}{5}\), what is the value of \(\tan x\)?
Explanation opens after your attempt
Correct Answer
B. -\(\frac{4}{3}\)
Concept
In the second quadrant, \(\sin x\) is positive and \(\cos x\) is negative. Since \(\sin x=\frac{4}{5}\), \(\tan x=-\frac{4}{3}\).
Why this answer is correct
The correct answer is B. -\(\frac{4}{3}\). In the second quadrant, \(\sin x\) is positive and \(\cos x\) is negative. Since \(\sin x=\frac{4}{5}\), \(\tan x=-\frac{4}{3}\).
Exam Tip
दूसरे चतुर्थांश में \(\sin x\) धनात्मक और \(\cos x\) ऋणात्मक होता है। \(\sin x=\frac{4}{5}\), इसलिए \(\tan x=-\frac{4}{3}\) है।
