Question

if cosecA=2x and cotA=2/x. thend find the value of 2(x²-1/x²)
​

Answer 1

Answer:

2 sin A.10A

Step-by-step explanation:

Cosec A =2x

sin A =1/2x ...... eqn1

cot A =2/x

cos A/sin A = 2/x

put sinA = 1/2x from eqn 1

cosA/(1/2x) = 2/x

cosA *2x= 2/x

so cosA= 1/x²

now 2(x²-1/x²)

2(1/cosA-cosA)

take cosA LCM

2(1-cos²A)/cosA

I konw 1-cos²A= sin²A

2sin²A/cosA

2sinA.sinA/cosA

2sinA.tanA ans...
