Question

9.
cosec A-sin A sec’A - tan’A
cosec A + sin A
sec? A + tan? A​

Answer 1

Answer:

1

Step-by-step explanation:

use identity...

(1/sinA - sinA)(1/cosA- cosA) (sinA/cosA + cosA/ sinA)

(1-sin^2A/ SinA) (1-cos^2A/ cosA) (sin^2A+cos^2A/ sinAcosA)

(cos^2 A/ sinA) (sin^2A/ cosA) (1/sinAcosA)

cosAsinA/ sinAcosA = 1
