What is the value of cos(150°)?

Sagot :

Given that cos(150°).

[tex]\cos (150^o)=\cos (180^o-30^o)[/tex][tex]\text{Use }\cos (180^o-30^o)=-\cos 30^o[/tex]

[tex]\cos (150^o)=-\cos (30^o)[/tex][tex]\text{Use }\cos (30^o)=\frac{\sqrt[]{3}}{2}\text{.}[/tex]

[tex]\cos (150^o)=-\frac{\sqrt[]{3}}{2}[/tex]

Hence the required value is

[tex]\cos (150^o)=-\frac{\sqrt[]{3}}{2}[/tex]
