Question

Prove that: (tanx-cotx)=(2sin2x-1)/(sinx cosx).​

Answer 1

Answer:

Step-by-step explanation:

2Sin²x - 1 / SinxCosx

=> 2Sin²x - (Sin²x + Cos²x) / SinxCosx

=> Sin²x - Cos²x / SinxCosx

=> Sin²x/SinxCosx - Cos²x/SinxCosx

=> Sinx/Cosx - Cosx/Sinx

=> Tanx - Cotx

=> R.H.S

Hence Proved.
