Answer 2

help?!!

Answer 3

\(\bf \textit{Cofunction Identities}
\\ \quad \\
sin\left(90^o-{\color{red}{ \theta}}\right)=cos({\color{red}{ \theta}})\qquad

cos\left(90^o-{\color{red}{ \theta}}\right)=sin({\color{red}{ \theta}})\)

what do you think?

Answer 4

hhhmm,...sorry,...i don't know

Answer 5

lemme put it this way then
\(\bf cos\left(90^o-{\color{red}{ \theta}}\right)=sin({\color{red}{ 75^o}})\)

Answer 6

i am really sorry i still don't get it:(

Answer 7

what about \(\bf cos\left(90^o-{\color{red}{ 75^o}}\right)=sin({\color{red}{ 75^o}})
\)

makes any sense?
