EXAMPLE: Find each value. π 19π 2π (b) tan − (c) sin (a) cos 3 3 4 Solution: (a) Since 2π 3π − π 3π π π = = − =π− 3 3 3 3 3 the reference number for 2π/3 is π/3 (see Figure (a) below) and the terminal point of 2π/3 is in Quadrant II. Thus cos(2π/3) is negative and (b) The reference number for −π/3 is π/3 (see Figure (b) below).

than zero are referred to as negative integers. Zero is an integer itself but it is neither positive nor negative. Therefore‚ in early times‚ the concept of zero was the harder to accept than negative numbers as people were aware of the loss and debt which is a negative phenomenon. But historically‚ in many cultures‚ zero was identified before the acceptance of the negative numbers. It leads to a conclusion that if zero is not there than there is no concept of negative numbers.
