Question

if 4x is equal to secant theta and 4 by x is equal to tan theta then the value of 8 into x square minus one by x square​

Answer 1

Answer:

Step-by-step explanation:

Hi ,

Given

here I am taking A instead of theta ,

4x = sec A --- ( 1 )

4/x= tan A -----( 2 )

we know the trigonometric identity

sec² A - tan² A = 1

( 4x )² - ( 4/x )² = 1 from ( 1 ) and ( 2 ),

16x² - 16 / x² = 1

16( x² - 1/x² ) = 1

2× 8 ( x² - 1 / x² ) = 1

Therefore ,

8( x² - 1 / x² ) = 1/2
