CONSTANTS:

• e = Base of natural logarithms = 2.71828
• log 10 (e ) = 0.434294
• log e (10 ) = 2.30259
• log 10 (N ) = log e ( N ) x 0.4343
• log e ( N ) = log 10 ( N ) x 2.3026
• 1 Radian = 57° .2958 = 57° 17' 45"
• log 10 ( 𝜋 ) = 0.49715
• 𝜋 = 3.14159265 
• 1 / 𝜋 = 0.318131
• 𝜋 / 180 = 0.01745 𝜋
• square ( 𝜋 ) = 9.8696
