What is (\tan x+\cot x) equal to?(\tan x+\cot x) किसके बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \sec x\cosec x )( \sec x\cosec x )
We have (\tan x+\cot x=\frac{\sin x}{\cos x}+\frac{\cos x}{\sin x}). Simplifying gives (\frac{1}{\sin x\cos x}=\sec x\cosec x).(\tan x+\cot x=\frac{\sin x}{\cos x}+\frac{\cos x}{\sin x}) है। सरलीकरण से (\frac{1}{\sin x\cos x}=\sec x\cosec x) मिलता है।
