Prove that 7cot - 3cosec = 3, Mathematics

Assignment Help:

If 7 cosec?-3cot? = 7, prove that 7cot? - 3cosec? = 3.

Ans:    7 Cosec?-2Cot?=7

P.T 7Cot? - 3 Cosec?=3

7 Cosec?-3Cot?=7

⇒7Cosec?-7=3Cot?

⇒7(Cosec?-1)=3Cot?

⇒7(Cosec?-1) (Cosec?+1)=3Cot?(Cosec?+1)

⇒7(Cosec2?-1)=3Cot?(Cosec?+1)

⇒7Cot2?=3 Cot? (Cosec?+1)

⇒7Cot?= 3(Cosec?+1)

7Cot?-3 Cosec?=3
