While finding the Sine of a certain angle x, an absent minded professor failed to notice hat his calculator was not in the correct angular mode. However he was lucky to get the right answer. The two least positive values of x for which the Sine of x degrees is the same as the Sine of x radians were found by him as ( m pi )/( n - pi )and ( p pi )/( q+ pi ) where m,n , p and q are positive integers . Suppose ( mn )/( pq) be denoted by the quantity 'L'. Now answer the following questions. Assume that f(x) is differentiable for all x.The sign of f'(x) is as follows : f'(x) gt 0on ( - oo , -4) f'(x) lt 0on ( - 4, 6) f' (x ) gt 0 on ( 6, oo) Let g(x) = f ( 10-2x ) . The value of g' ( L) is
