Did you want the identities? Hope this helps you then. http://www.purplemath.com/modules/idents.htm I got some other interesting staff for you. \[\color{blue} {Sin~x} \color{red} {=} \color{blue} {\sqrt{1-Cos^2x}}~~~~~~~~~and\]\[\color{blue} {Cos~x} \color{red} {=} \color{blue} {\sqrt{1-Sin^2x}}\] being that \[\color{green} {Sin~^2x} \color{red} {=} \color{green} {1-Cos^2x}~~~~~and\]\[\color{green} {Cos~^2x} \color{red} {=} \color{green} {1-Sin^2x}\] Ask anytime, I can tell you more....

OpenStudy (anonymous):

nevermind but thank you i was asking fro like|dw:1387119630855:dw| but someone helped me

OpenStudy (anonymous):

like sin=opp/hyp cos=adj/hyp

OpenStudy (solomonzelman):

\[\huge\color{blue}{\huge {\bbox[5pt,cyan,border:2px solid purple]{SOH~~~~CAH~~~~TOA}}}\]

OpenStudy (anonymous):

OpenStudy (solomonzelman):

Do you see what I am doing or I am going too fast?

OpenStudy (anonymous):

i see

OpenStudy (solomonzelman):

\[\sqrt{394}~~≈~~19.85\]

OpenStudy (anonymous):

weere did u get that

OpenStudy (solomonzelman):

got what?\[13^2+15^2=394~~~~~~~~~~~~~PATHEGORIAN\]\[\sqrt{13^2+15^2}=\sqrt{394}~≈~19.85\]
