    • How do you graph a function?

      graphs the function: its graph being the curve y = f(x) in the (x; y)-plane. C C numbers to complex numbers, or equivalently points in the (x; y)-plane to points in the (u; v) plane. Hence its graph de ̀„nes a surface u = u(x; y) and v = v(x; y) in the four-dimensional space with coordinates (x; y; u; v), which is not so easy to visualise.

    • What is a polar representation of a complex number?

      We know that for any real number x, ex can be expressed as x2 x3 ex = 1 + x + + + 2! 3! n! ez = 1 + z + + + 2! 3! n! That is, r is the magnitude of z. We call rei the polar representation of the complex number z. Note: In the polar representation of complex number, we always assume that r is non-negative.

    • What is a complex trigonometric function?

      Being linear combinations of the entire functions exp(§iz), they themselves are entire. Their derivatives are The complex trigonometric functions obey many of the same properties of the real sine and cosine functions, with which they agree when z is real. For example, cos(z)2 + sin(z)2 = 1 ; and they are periodic with period 21⁄4.

    • What is a complex-valued function?

      A complex-valued function de nes a curve in the complex plane. The derivative of w(t) with respect to t is de ned to be the function (This is just like the de nition of the derivative of a vector-valued function { just di erentiate the components.) The derivative can be viewed as the tangent vector to the complex curve.

      The complex exponential The exponential function is a basic building block for solutions of ODEs. Complex numbers expand the scope of the exponential function, and bring trigonometric functions under its sway. 6.1. Exponential solutions. The function et is de ned to be the so- lution of the initial value problem x _ = x, x(0) = 1.

    • 13 Visualizing Complex-valued Functions

      In this lab we present methods for analyzing complex-valued functions visually, including locating their zeros and poles in the complex plane. We recommend completing the exercises in a Jupyter Notebook. Representations of Complex Numbers z = x + iy polar coordinates z = rei complex number can be written in as where r = jzj = px2 + y2 magnitude z

      The complex numbers may be represented as points in the plane, with the real number 1 represented by the point (1;0), and the complex number irepresented by the point (0;1). The x-axis is called the \real axis," and the y-axis is called the \imaginary axis." For example, the complex numbers 1, i, 3 + 4iand 3 4iare illustrated in Fig 1a. 1 i 3 ...
