# cos(tan + cot) = csc 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

cos(tan + cot) = csc
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

then on the left..

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

• ### Solve this equation algebraically: (1-sin x)/cos x = cos x/(1+sin x) --- I know the answer is an identity, and when graphed, it looks like cot x

Solve this equation algebraically:(1-sin x)/cos x = cos x/(1+sin x)---I know the answer is an identity, and when graphed, it looks like cot x. I just don't know how to get there. I tried multiplying each side by its conjugate, but I still feel stuck. This is what I have so far:cos^2(x)/cos x + sin x = cos x - sin x/cos^2(x)...but I'm not really sure how to get to the answer. Help please?Thank you!
