     delta x taken from x sub k equal to a to x sub k equal to b minus delta x
     equals the integral from a to b of small f of xdx equals capital F of x
     between limits a and b equals capital F of minus capital F of a equals
     capital A
   • x approaches x nought; or x tends to x nought
   • the logarithm of c to the base b is equal to n
   • the limit of f of x tends to x nought is not equal to f of x nought

a) ϕ of z is equal to b, square brackets, parenthesis, z divided by c sub m plus
   two, close parenthesis, to the power of m over m minus 1, minus 1, close
   square brackets.
b) ϕ
     оf z is equal to b, multiplied by the whole quantity: the quantity two plus z
   over c sub m, to the power m over minus 1, minus 1.
