only simplify one side to equal csc

so far I got this far:

[((cos)(sin))/(cos)] + [((cos)(cos))/(sin)] = csc

I don't know what to do next

sin+cos^2/sin=sin+(1-sin^2)sin=sin+csc-sin=csc

**Reiny**, Friday, March 18, 2011 at 9:19pmYou will need a common denominator of sinxcosx in your fraction to get

LS = cosx(sin^2x /(sinxcosx) + cos^2x/(sinxcosx))

= cosx (sin^2x + cos^2x)/(sinxcosx)

= cosx(1)/(sinxcosx)

= 1/sinx

= cscx

BTW you cannot just use the operators, there has to be some "angle" after it

e.g. to say tan = sin/cos is not acceptable and mathematical gibberish.
