Question

cotA ×CosA+sinA=cosecA​

Answer 1

Answer:

Step-by-step explanation:

Cot AXCOSA+SINA=COSEC A

THEN USING COTA=COSA/SINA

COSA XCOSA+SINA=COSEC A

_____

SINA

COS SQUARE A +SINA=COSECA

____________

SINA

COS SQAURE A+SIN SQURE A

______________________

SinA

USING COS SQUARE THETA +SIN SQURE THETA=1

WE GET

(1)

____________=COSECA

SINA

COSEC A=COSEC A

HENCE PROVED

HERE WE GO DEAR

✌

Answer 2

cotA x cosA + sinA = cosecA

cosA/sinA x cosA + sinA = cosecA

Cos^2A/sinA + sinA = CosecA

Cos^2A + sin^2A/sinA = cosecA

1/SinA = cosecA

cosecA = cosecA

hence, proved.
