Question

if 7cosec theta - 3cot theta = 7 , prove that 7cot theta-3cosec theta=3​

Answer 1

$●\large\sf \bf \underline\purple{ your\: \: answer \: !!}$

Step-by-step explanation:

7cosec - 3cot =7

7cosec-7-3cot

7(cosec-1)=3cot

7(cosec-1)(cosec+1)=3cot(cosec+1)

7(cosec^2-1)=3cot(cosec+1)

7cot^2=3cot(cosec+1)

7cot 3(cosec+1)

7cot-3cosec+3

7cot-3cosec=3

Step-by-step explanation:

7cosec - 3cot =7

7cosec-7-3cot

7(cosec-1)=3cot

7(cosec-1)(cosec+1)=3cot(cosec+1)

7(cosec^2-1)=3cot(cosec+1)

7cot^2=3cot(cosec+1)

7cot 3(cosec+1)

7cot-3cosec+3

7cot-3cosec=3
