Question

If tanA + cot A = 2 , then what is the value of tan²A + cot²A​

Answer 1

$\tt \purple {Please Mark it BRAINLIEST}$

GIVEN:-

$\tan(a) + \cot(a) = 2$

Let's square on both the sides

Apply this identity:

(a + b )² = a² + b² +2ab

(a - b )² = a² + b² - 2ab

Therefore,

$( { \tan(a) + \cot(a) )}^{2} - 2 \tan( \alpha ) \times \cot( \alpha )$

Substitute the value

${2}^{2} - 2 \times \tan( \alpha ) \times \frac{1}{ \tan( \alpha ) }$

$4 - (2 \times 1) \\ 4 - 2 \\ = > 2 \: answer$
