The above snippet shows the exponential of a complex number. Example 5: Complex Trigonometric Functions Python provides a range of complex trigonometric functions, including “cmath.sin()”, “cmath.cos()”, “cmath.tan()”, “cmath.asin()”, “cmath.acos()”, and “cmath.atan()”. ...
Trigonometric form of a complex number: Similar to how we express the coordinates of a point on the unit circle using trigonometric functions, we can express the point {eq}a+bi {/eq} (in the complex plane) using trigonometric functions by forming the circle centered at th...

Trigonometric functions describe the relationship between an angle and the side of a given right triangle using three functions: sine, cosine, and tangent. Use examples to learn how each of these is calculated and applied to real numbers. ...
Trigonometric functions - Wikipedia 9. How to use the IMCSCH function What is the IMCSCH function? The IMCSCH function calculates the hyperbolic cosecant of a complex number in x + yi or x + yj text format. The letter j is used in electrical engineering to distinguish between the imaginary...
