... 12, but with one additional wrinkle. Page 12 defines f + g to be the function with domain dom f ∩ dom g whose value at x is f (x) + g(x), and defines multiplication similarly. The extra wrinkle is that we also need to remove any removable singularities. Algebraically, this amounts to canceling any c ...

... The modulus, or length, of a complex no. is the distance from the origin to the point representing the complex number on an Argand diagram. We use 2 lines either side of a complex no. to represent the modulus. E.g the modulus of 3 - 4i is written |3 - 4i|. This is then the distance from (0,0) to (3, ...

... and imaginary parts, respectively, give the identity eit = cos t + i sin t. It is worth pointing out that this is not entirely rigorous, because we have not yet proven that power series make sense when we allow the variable to be a complex instead of real. We will make this rigorous over the next fe ...

... You can see in the graph of f(x) = x2 + 1 below that f has no real zeros. If you solve the corresponding equation 0 = x2 + 1, you find that x = ,which has no real solutions. However, you can find solutions if you define the square root of negative numbers, which is why imaginary numbers were invent ...

... Dividing complex numbers The second important technique shown in this section is demonstrated in Examples 2.3 and 2.4. It is difficult to work with complex numbers in the denominator of an expression, so it can be very useful to be able to make the denominator real. This is sometimes known as “reali ...

... relates a number and its complex conjugate? 2. We measure the “size” of a real number by using absolute value: |x| is the distance from the real number x to the origin. In the same way we define the absolute value of a complex number to be its distance from the origin. This distance will always be a ...
