OpenStudy (solomonzelman):

Works.

OpenStudy (solomonzelman):

Works.

OpenStudy (solomonzelman):

\(\large\color{blue}{ \rm π=180º}\) hence your expression is \(\large\color{blue}{ \rm cos(315) }\)

OpenStudy (solomonzelman):

\(\large\color{blue}{ \rm cos(315) =cos(360-45)=}\) \(\large\color{blue}{ \rm =cos(360)cos(45)+sin(360)sin(45)=?}\)

OpenStudy (solomonzelman):

\(\large\color{blue}{ \rm sin(360)=0,~~~cos(360)=1}\) \(\large\color{blue}{ \rm sin(45)=cos(45)=√2~/~2}\)

OpenStudy (solomonzelman):

Go for it.
