Question

(sec A + tan A) (1 - sin A ) ​

Answer 1

Answer:

CosA

Step-by-step explanation:

(1/COSA + SINA/COSA)(1-SINA)

(1+SINA/COSA)(1-SINA)

(1^2-Sina^2/CosA)

(COSA^2)/CosA

CosA

Answer 2

Answer:

cosA

Step-by-step explanation:

(secA+tanA)(1-sinA)

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

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

1-sin²A/cosA

cos²A/cosA

=cosA
