Question

Please verify how
`(1-cos(x))/(sin(x)) =(sin(x))/(1+cos(x))`

Answer 1

Answer/Step-by-step explanation:

`(1-\cos \left(x\right))/(\sin \left(x\right))=(\sin \left(x\right))/(1+\cos \left(x\right))`

When you have an equation like this, you can start from either side. So, let us start from the left side.

`\underline{\mathrm{Left\:side:}} \quad(1-\cos \left(x\right))/(\sin \left(x\right))`

`\sf{Rewrite\: using \:Trig \:identities=(\sin \left(x\right))/(1+\cos \left(x\right))}\\\\\mathrm{Therefore,\: it \:is \:true}`
