Question

The value of cosec²(90° -0) - tan²0 is...​

Answer 1

Answer:

1

Step-by-step explanation:

Sec^2 $ - tan^2 $=1

General identity.

Answer 2

Step-by-step explanation:

${ \csc} ^{2}(90 - 0) - { \tan}^{2} (0)$

${ \sec }^{2} (0) - { \tan }^{2} (0)$

${ \sec }^{2} (x) - { \tan}^{2} (x) = 1$

therefore

${ \sec}^{2} (0) - { \tan }^{2} (0) = 1$
