(4)

Updated on 14 March 2008

Proving questions are good.
Proving questions are important.
Proving questions helps you remember the formulas.
So don’t be lazy and don’t always skip the proving questions in your homework!

Show that

${2-cosec^2 x}/{cosec^2 x+2 cot x}={sin x-cos x}/{sin x+cos x}$

Ignore at your peril!

頑張って!!!
