For Sine, press “Ctrl” with “s,” and then “s.” This is shown on the Braille
display as, sin(.
For Arc Sine, press “Ctrl” with “s,” then “a.” This is displayed as asin(.
For Hyperbolic sine, press “Ctrl” with “s,” then “h.” This is displayed as sinh(.
In order to calculate the sine of a 30 degree angle you would type the
following: Ctrl with s, then “s,” 30 and then” ).” Press “Enter” and your
answer is displayed as 0.5.
Cosine Functions:
For Cosine, you would press “Ctrl” with “i” and then you would press “i” This
is displayed as cos(.
For Arc cosine, press “Ctrl,” with “i” then, “a.” This is displayed as acos(.
For Hyperbolic cosine, press “Ctrl” with “i” then, “h.” This is displayed as
cosh(.
For example, to calculate the cosine of the 30 degree angles, you press:
Ctrl with i, I, 30 and then “)”. Then, press “Enter.” Your answer will be given
as 0.8660254.
Tangent Functions:
For Tangent, press “Ctrl” with “t” and then “t.” This is displayed as tan(.
For Arc tangent, press “Ctrl” with “t” then “a.” This is displayed as atan(.
For Hyperbolic tangent, press “Ctrl,” with “t,” then, “h.” This is displayed as
tanh(.
For example, to calculate the tangent of the 30 degree angles, you press:
Ctrl with t, T, 30 and then “)”. That is, tan(30) which gives you the result of
0.57735027.
