Question 238707
Since the movement of the pole is given in radians, we should figure out how many radians are in 5 degress:
1 degree = {{{pi/180}}} radians. So 5 degrees = {{{5*(pi/180) = pi/36}}} radians.<br>
So now the problem is to find out how long it will take to pole to move {{{pi/36}}} radians if it moves 0.0017 radians per year. So we will divide:
{{{(pi/36)/0.0017}}}
Changing this division to multiplying by the reciprocal may make this easier:
{{{(pi/36)*(1/0.0017)}}}
which simplifies to:
{{{pi/(36*0.0017)}}}
