In the following, u,v,w, are functions of x; a,b,c,n are constants[restricted if indicated]; e=2.71828... is the natural base of logarithm of u[i.e. the logarithm to the base e] where it is assumed that u>0 and all angles are in radians.

dc/dx = 0

d(cx)/dx = c

d(cxn)/dx = ncxn-1

d(u+v+w+...)/dx = du/dx + dv/dx + dw/dx + ...

d(cu)/dx = c du/dx

d(uv)/dx = u dv/dx + v du/dx
