this is a heat transfere question .. please solve it fast

Q2: A thin rod (L=30cm,D=0.5cm and k=65W/mC) is subjected to environmental condition of T=20C,h=50W/m2C. If the rod is insulated at the end part and subjected to heat source with 200C at (x=0) : Derive the temperature distribution for the whole rod. Calculate the heat losses from the rod and its efficiency when the length is decreased to the half value. If general solution equation is: =C1coshmx+C2sinhmx
