following series: 3,7, 39, 41, 57, 84, 91, 95, 110,
144
070.5
067.1
O52.5
057
O 65.5
we know that
Sine or Cosine of a Half Angle is giving by the formulas
step 1
Find the value of Sin(30)
so
substitute the given values
cos(60)=1/2
step 2
Find the value of Cos(30)
substitute the given values in the formula above
step 3
Find the value of Cot(60)
REmember that
Cot=cos/sin
so
substitute
cot(60)=cos(60)/sin(60)
cot(60)=(1/2)/(V3/2)=V3/3
Is that / fouse to be a divided sign
