ctg^5*csc^2x

OpenStudy (ageta):

=c^4g^5stx

OpenStudy (anonymous):

that equaks to c^6g^5stx angelicatorrea11

OpenStudy (ageta):

s/he is wrong

OpenStudy (jhannybean):

What is ctg. Cotangent? O_o

zepdrix (zepdrix):

ya c: i guess so

OpenStudy (jhannybean):

\[\sf (\cot(x))^5(\csc(x))^2\] I'm gussing.

OpenStudy (jhannybean):

You know \(\sf \cot^2(x) = \csc^2(x) - 1 ~ , ~ \csc^2(x) = \cot^2(x) +1\)\[\sf [\cot^2(x)\cdot \cot^3(x) ](1+\cot^2(x))\]\[\sf (1-\csc^2(x))(cot^3(x))(1+\cot^2(x))\]

OpenStudy (jhannybean):

\[\sf \color{red}{(1-\csc^2(x))}(cot^3(x))\color{red}{(1+\cot^2(x))}\]\[=\sf (cot^3(x))\color{red}{(1-csc^4(x))}\]
