Question

if x sin a = 1 and cot a = y, find the value of x^2 - y^2​

Answer 1

Answer:

${x}^{2} - {y}^{2} = 1$

Step-by-step explanation:

$x = \frac{1}{ \csc( \alpha ) } \\ \\ y = \sin( \alpha ) \\ \\ {x}^{2} - {y}^{2} = { \csc( \alpha ) }^{2} - { \cot( \alpha ) }^{2} \\ \\ {x}^{2} - {y}^{2} = 1$
