Answer 1

Answer:

-fax fax cos teta side normal

Answer 2

Step-by-step explanation:

(cosA.cotA)/(1-sinA) = 1+cosecA

{cotA= cosA/sinA}

(cosA×cosA/sinA)/(1-sinA)

cos²A/sinA(1-sinA)

{cos²A+sin²A=1

{cos²A+sin²A=1cos²A=1-sin²A}

1-sin²A/sinA(1-sinA)

{applying a²-b²=(a+b)(a-b)}

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

(1+sinA)/sinA

1/sinA+sinA/sinA

{1/sinA=cosecA}

cosecA+1
