(\tan\(\frac{\pi}{2}+x\)) किसके बराबर है?

What is (\tan\(\frac{\pi}{2}+x\)) equal to?

Explanation opens after your attempt
Correct Answer

A. \(-\cot x\)

Explanation

Simple Explanation

\(\frac{\pi}{2}+x\) पर \(\tan\) बदलकर \(\cot\) होता है और चिन्ह ऋणात्मक होता है। इसलिए (\tan\(\frac{\pi}{2}+x\)=-\cot x)। / At \(\frac{\pi}{2}+x\), \(\tan\) changes to \(\cot\) with a negative sign. Hence (\tan\(\frac{\pi}{2}+x\)=-\cot x).
