Complex Number Rules.
Is this like having a complex number?
Any complex number, say z, can be expressed using a pair of real numbers. .
And this is actually called the argument of the complex number.
This is a function that you input a complex number and it will output the real part.
The IMCOS(string) returns the cosine of a complex number.
The IMARGUMENT(complex number) returns the argument of a complex number of form x+yi.
The IMSIN(string) function returns the sine of a complex number.
An argument of the complex number z= x+ iy, denoted arg(z), is defined in two equivalent ways.
The IMEXP(string) returns the exponential of a complex number.
The signum of a given complex number z is the point on the unit circle of the complex plane that is nearest to z.
The IMTAN(string) function returns the tangent of a complex number.
The IMPOWER(string) returns a complex number raised to a power.
The IMCOSH(string) returns the hyperbolic cosine of a complex number.
So if c is an imaginary number, or some type of complex number, we don't even know whether this is necessarily an imaginary number. .
The IMSQRT(string) returns the square root of a complex number.
The IMLN(string) returns the natural logarithm of a complex number.
Under both definitions,it can be seen that the argument of any non-zero complex number has many possible values: firstly, as a geometrical angle, it is clear that whole circle rotations do not change the point, so angles differing by an integer multiple of 2π radians(a complete circle) are the same, as reflected by figure 2 on the right.
The IMLOG2(string) returns the base-2 logarithm of a complex number.
Because a complete rotation around the origin leaves a complex number unchanged, there are many choices which could be made for φ by circling the origin any number of times. This is shown in figure 4, a representation of the multi-valued(set-valued) function f( x, y)= arg( x+ i y){\displaystyle f(x, y)=\arg(x+iy)}, where a vertical line(not shown in the figure) cuts the surface at heights representing all the possible choices of angle for that point.
Now, if we wanted to represent-- let's say we had the complex number.
Under both definitions,it can be seen that the argument of any non-zero complex number has many possible values: firstly, as a geometrical angle, it is clear that whole circle rotations do not change the point, so angles differing by an integer multiple of 2π radians(a complete circle) are the same, as reflected by figure 2 on the right. Similarly, from the periodicity of sin and cos, the second definition also has this property. The argument of zero is usually left undefined.
So the tangent of this angle, which we called the argument of the complex number.
In a demonstration to the American Mathematical Society conference at Dartmouth Collegeon 11 September 1940,Stibitz was able to send the Complex Number Calculator remote commands over telephone lines by a teletype.
It would be b-- this is a real number-- but this tells us how much the i is scaled up in the complex number z.
Definition==Given an orthonormal basis, any pure state formula_3 of a two-level quantum system can be written as a superposition of the basis vectorsformula_4 and formula_5,where the coefficient or amount of each basis vector is a complex number.
