{\tan ^{ - 1}}\frac{{{c_1}x - y}}{{{c_1}y + x}} + {\tan ^{ - 1}}\frac{{{c_2} - {c_1}}}{{1 + {c_2}{c_1}}} + {\tan ^{ - 1}}\frac{{{c_3} - {c_2}}}{{1 + {c_3}{c_2}}} + ... + {\tan ^{ - 1}}\frac{1}{{{c_n}}}

is equal to

View answer and explanation

Correct option: C

{\tan ^{ - 1}}\frac{x}{y}

Option C is correct because the given expression simplifies to

{\tan ^{ - 1}}\frac{x}{y}

due to the telescoping nature of the series.
