Question

Secα+tanα=p then what is the value of secα-tanα

Answer 1

Hey, !!..


Sec¢+ tan¢ = 1

Now by using rationalising process

1/Sec¢ + tan¢ = 1/p

1/ sec¢ + tan¢ × sec¢ - tan¢ /sec¢ - tan¢ [ multiplying by sec¢ - tan¢ on numerator and denominator]

We got

Sec¢ - tan¢ / sec²¢ - tan²¢ = 1/P

Sec¢ - tan¢ / 1 = 1/p

Sec¢ - tan¢ = 1/p

Hope it helps !!!
