It might seem random, but there's a story behind it. A brilliant German mathematician named Emmy Noether used "Zahlen" (meaning "numbers" in German) to represent integers, and the letter Z stuck around as a tribute to her work. Z has some cool cousins too: · N: This is the "Natura...

–The cotangent function is odd, meaning that it changes sign when x is changed to -x. This means that it is symmetric about the origin (0,0). –The range of the cotangent function is all real numbers except for those in between two vertical asymptotes (where the tangent function is un...
