The sum of (3.6 × 10^3) and (6.1 × 10^3) is <span>9.7 × 10^3.</span>
Using the sine rule:
sinx/37 = sin42/31
sinx = 37 x sin42/31
x = (i dont have a calulator but use inverse sign to get this answer)
If 
, then the area between the graph of 
and the <em>x</em>-axis for non-negative <em>x</em> is given by the integral,
Let 
and 
; then the integral is equivalent to
Circle means it is a geomatical product
