Question

Prove that cotA . cosA + sinA = cosecA​

Answer 1

Answer:

Step-by-step explanation:

Here's your answer.

Answer 2

Answer:

COT A * COS A + SIN A

COS A/ SIN A * COS A + SIN A

COSA*COSA/SIN A + SIN A

COSA*COSA/SINA + SINA*SINA/SINA

(COSA*COSA + SINA*SINA = 1)

1/SIN A (1/SINA=COSECA)

COSEC A = COSEC A
