Question

if sec theeta + tan theeta = m , and sec theeta - tan theeta = n , then prove that under root mn = 1.

Answer 1

Hi ,



Sec theta + tan theta= m ----( 1 )

Sec theta - tan theta= n -----( 2 )

Multiply ( 1 ) and ( 2 ) , we get

Sec² theta - tan² theta = mn

1 = mn

mn = 1

√mn = √1

√mn = 1

I hope this helps you.
