Question

What happened (1-tan)2+(1-cot)2=?

Answer 1

$\mathfrak{here \: is \: your \: answer} \\ \mathfrak{ (1 - tan \theta) {}^{2} + (1 - cot \theta) {}^{2} } \\ 1 + {tan}^{2} \theta - 2tan \theta + 1 + {cot}^{2} \theta - 2cot \theta \\ {sec}^{2} \theta + cosec {}^{2} \theta - 2tan \theta - 2cot \theta \\ {sec}^{2} \theta + cosec {}^{2} \theta - 2(tan \theta + cot \theta) \\ \mathfrak \red{ \underline{ \underline {hope \: my \: answer \: will \: help \: you}}}$
