Cosine Functions: 
 
For Cosine, you would press “Enter” with “dots 1-4”, and then you would 
press “c”. This is displayed as cos(. 
 
For Arc cosine, press “Enter”, with “dots 1-4”, then, “a”. This is displayed 
as acos(. 
 
For Hyperbolic cosine, press “Enter” with “dots 1-4”, then, “h”. This is 
displayed as cosh(. 
For example, to calculate the cosine of the 30 degree angles, you press: 
Enter with dots 1-3, C, 30 and then “)”. Then, press “Enter”.    Your 
answer will be given as 0.8660254.

 

 

Tangent Functions: 
 
For Tangent, press “Enter” with “dots 2-3-4-5” and then “t”. This is 
displayed as tan(. 
For Arc tangent, press “Enter” with “dots 2-3-4-5” then “a”. This is 
displayed as atan(. 
For Hyperbolic tangent, press “Enter”, with “dots 2-3-4-5”, then, “h”. This 
is displayed as tanh(. 
For example, to calculate the tangent of the 30 degree angles, you 
press: Enter with dots 2-3-4-5, T, 30 and then “)”. That is, tan(30) which 
gives you the result of 0.57735027. 

 

 

Common logarithm 
For Common logarithm, press “Enter” with “dots 1-2-3”, and then “n”. 
This is displayed as log(. 
For example, to calculate the common logarithm of the 100, you press: 
Enter with dots 1-2-3, N, 100 and then “)”. That is, log(100) which gives 
the result 2.
