+118724 Find sin t and cos t for the given value of t.
t = 945°
945-360-360=225
225-180=45
so
945 is equivalent to 225 degrees which is in the 3rd quadrant and the equivalent acute angle is 45 degrees.
Sin and cos are both negative in the 3rd quadrant.
\(sin(945)=cos(945)= - cos(45) =-sin(45)=\frac{-1}{\sqrt2}\)
