I have a graph which represents the heat flux around circumferential angle of a cylinder. i need a polynimial equation (heat flux = a +( b* theta) + (c*(theta)^2 ) + d*(theta)^3 + e *(theta)^4) for the conditions like 0 to 45, 45 to 180 and 180 to 360 degree . can any one explain me how to make fourth order polynomial equation for the specfic degree interval?
