Question

1/ 1+cot^2 theta +1/1+ tan^2 theta? please answer this question​

Answer 1

Step-by-step explanation:

HEY MATE .......

$1 + {tan}^{2} thetha \: = {sec}^{2} thetha \\ \\ 1 + {cot}^{2} thetha = {cosec}^{2} thetha (identity) \\ \\ sec \: thetha \: = \frac{1}{cos \: thetha} \\ \\ cosec \: thetha = \frac{1}{sin \: thetha} \\ \\ {sin}^{2} thetha + {cos}^{2}thetha = 1 \\ \\ = \frac{1}{ {sec}^{2} } thetha \: + \frac{1}{ {cosec}^{2} } thetha \: \\ \\ {cos}^{2} thetha + {sin}^{2} thetha = 1$
