Question

If tan A=4/3,then prove value of tan 2A​

Answer 1

tan a = 4/3 , we know

tan 2a = 2tan a / (1 - tan^2 a)

= 2 *4/3/{(1 - 16/9)}

= (8/3)/(-7/9)

= - 24/7

Answer 2

tan a = 4/3 , we know

tan 2a = 2tan a / (1 - tan^2 a)

= 2 *4/3/{(1 - 16/9)}

= (8/3)/(-7/9)

= - 24/7

have a good day ahead
