Question 59557
<pre>Convert -60° to radians. express the answer as a multiple of <font face = "symbol">p</font>
<font size = 4 color = "darkgreen"><b>
                                                                    <font face = "symbol">p</font>
To convert degrees to radians, put degrees over 1 and multiply by ——————
                                                                   180°

 
                                            180°
To convert radians to degrees, multiply by ——————
                                             <font face = "symbol">p</font>

This problem is to convert degrees to radians, so,

                   -60°
Put -60° over 1:  ——————
                     1 

              <font face = "symbol">p</font> 
Multiply by ——————
             180°

 -60°      <font face = "symbol">p</font>
—————— · ——————
  1       180° 

Divide the -60° on top and the 
180° on the bottom both by 60°

  -1
 <s>-60°</s>      <font face = "symbol">p</font>
—————— · ——————
  1       <s>180°</s> 
           3
 
      -1<font face = "symbol">p</font>          <font face = "symbol">p</font>
     —————  or  - ———
       3           3
