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

  • Math -

    then on the left..

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

  • Math -

    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.

    Hello all, In our math class, we are practicing the trigonometric identities (i.e., sin^2(x)+cos^2(x)=1 or cot(x)=cos(x)/sin(x). Now, we are working on proofs that two sides of an equation are equal (for example, sin(x)*csc(x)=1; sin(x)csc(x)=sin(x)/sin(x)=1; …
