Question

The value of -101 by cos^2A *+ 101 by cot^2 A
​

Answer 1

Answer:

-101

Explanation:

$\frac{ - 101}{ { \cos}^{2} } + \frac{101}{ { \cot }^{2} } \: = \frac{ - 101}{ { \cos }^{2} } + \frac{101}{ \frac{ ( { \cos}^{2} ) }{ { \sin}^{2} } }$

so

$\frac{ - 101}{ { \cos }^{2} } + \: \frac{101 { \sin }^{2} }{ { \cos}^{2} }$

then take -101 common

$- 101 \frac{(1 - { \sin }^{2} )}{ { \cos }^{2} }$

as we know

$1 - { \sin}^{2} \: = { \cos }^{2}$

therefore

$- 101 \frac{ { \cos}^{2} }{ { \cos }^{2} }$

${ \cos }^{2} \: \: will \: cancel \: \cos^{2}$

thus answer will be -101
