Trignometry FunctionEdit

Relation of right triangle sides are defined as trigonometry functions. They are

Trignometry Function Definition Mathematical Formula Graphs
Sin Opposite side over hypotnuse    
Cos Adjacent side over hypotnuse    
Tang Opposite over Adjacent    
Cotang Adjacent over opposite    
Sec 1 over opposite    
Cosec 1 over adjacent    

The Sin functionEdit

Trignometry

 

Calculus

 

Eucleur's complex circle

 

In solving wave equation of the form   gives Sin function as a wave function

 

From above, when
