Question

Secot Tano=4, then
seco-Tano= ?​

Answer 1

Answer:

1/4

Step-by-step explanation:

G.T

secx+tanx=4

(sec^2x-tan^2x)=1

(secx+tanx)(secx-tanx)=1

(4)(secx-tanx)=1

secx-tanx=1/4

Answer 2

seco + tano = 4

we know that ( sec 0 - tan 0) square= 1

seco - tano . seco + tano = 1

seco - tano = 1/4
