The derivative of sinh x is cosh x and the derivative of cosh x is sinh x; this is similar to trigonometric functions, albeit the sign is different (i.e., the derivative of cos x is −sin x). The Gudermannian function gives a direct relationship between the circular functions and the hyperbolic ones that does not involve complex numbers.
The trigonometric form of a complex number z= a+ biis z= r(cos + isin ); where r= ja+ bijis the modulus of z, and tan = b a. is called the argument of z. Normally, we will require 0 <2ˇ.

The complex numbers then form a linear vector space and addition of complex numbers can be performed graphically in exactly the same manner as for vectors in a plane.
Complex numbers are numbers of the form $ z = x + iy $, where $ x $ is said the be the real part, written as $ text{Re }z $, and $ y $ is said to be the imaginary part, written as $ operatorname{Im}z $.
You can also put complex numbers in your graphing calculator, and even perform complex conversions on the graphing calculator later. Polar (Trig) Form of a Complex Number Again, we can write the rectangular form of a complex number in the form z = x + yi , or more commonly, z = a + bi .
Trigonometry and complex numbers Each point P in the plane may also be identified by a pair of numbers r , where r is the distance from P to the origin, OP , and θ …
Modern definitions express trigonometric functions as infinite series or as solutions of certain differential equations, allowing the extension of the arguments to the whole number line and to the complex numbers.
