Source:  x =  
In degrees (for radians):  x * π / 180 =  
In radians (for degrees):  x * 180 / π =  
Sine (for °):  sin x =  
Cosine (for °):  cos x =  
Tangent (for °):  tg x =  
Arcsine (for °):  arcsin x =  ° 
Arccosine (for °):  arccos x =  ° 
Arctangent (for °):  arctg x =  ° 
The power of e:  e^{x} =  
Natural logarithm:  log_{e}x =  
Power: Number in power:
