8(1 z2)3z; (c) 1=(2z + 1)2; (d) e1=z=z2. 8. Prove the following version of complex L’Hospital: Let f (z) and g(z) be two complex functions defined on jz z0j < r for some r > 0. Suppose that f (z0) = g(z0) = 0, f (z) and g(z) are differentiable at z0 and g0(z0) 6= 0. Then.
In these notes, we examine the logarithm, exponential and power functions, where the arguments∗ of these functions can be complex numbers. In particular, we are interested in how their properties differ from the properties of the corresponding real-valued functions.† 1. Review of the properties of the argument of a complex number
The problems covered include finding the general value of log(1+i)+log(1-i), evaluating logarithms of expressions involving trigonometric functions, and using properties of logarithms to simplify complex logarithmic expressions.

Question 1 By finding a suitable Cartesian locus in the complex z plane, shade the region R that satisfies the inequality z z− ≤ +3 3i . x y+ ≥ 0
Complex logarithm Complex power function De–nition Properties 1. Complex exponential The exponential of a complex number z = x +iy is de–ned as exp(z) = exp(x +iy) = exp(x)exp(iy) = exp(x)(cos(y)+i sin(y)): As for real numbers, the exponential function is equal to its derivative, i.e. d dz exp(z) = exp(z): (1) The exponential is therefore ...
