 if y = x sinx , find dy/dx from first principles
----------------------------------------------

-----------------------------------------------
f(x) = x sinx
f(x+h) = (x+h) sin(x+h)
find lim { f(x+h) - f(x)} / h  as h-->0
for that group, simplify  using sinC-sinD formula : trig. formulae
and use lim (sinh / h ) = 1 as h-->0
answer and  some steps are given below
