R Introduction: Part I
Complex Numbers
Complex numbers have a significant role in various advanced fields such as quantum mechanics, signal processing, and physics, intertwining with calculus.
While this course focuses on the foundational elements of R, it's important to at least acknowledge complex numbers as a numerical type within R's language. A complex number is composed of a real part (denoted as a) and an imaginary part (denoted as b). This forms an expression a+bi, which we call a complex number, where i represents the imaginary unit with the property that i^2 = -1.
To represent a complex number in R, you would use the notation a + bi. For instance, we can create a complex number where the real part is 5 and the imaginary part is -3.
Remember that the arithmetic operations we've learned can be applied to all the types of numbers we've discussed.
Tarea
- Declare an
integernumber20and assign it to the variablenum. - Create a
complexnumber with a real part of10and an imaginary part of-5and assign it to the variablecompl. - Perform an addition operation between
numandcompland assign the result tores. - Determine and display the type of
res.
Since adding an integer to a complex number results in a complex number, the type of res is "complex". This is because complex numbers include real numbers and integers within their broader numerical system.
