HYP SIN, HYP COS, HYP TAN

Purpose

Returns the value of the corresponding hyperbolic trigonometric function value for the argument.

Format

HYP SIN     (argument)
             └──┬───┘ 
       Numeric expression
   
HYP COS     (argument)
             └──┬───┘ 
       Numeric expression
   
HYP TAN     (argument)
             └──┬───┘ 
       Numeric expression

*The parenthesis enclosing the argument can be omitted when the argument is a numeric value of variable.

Example

HYP SIN(1.5)

Parameters

argument: Numeric expression

HYP SIN	argument	≦ 230.2585092
HYP COS	argument	≦ 230.2585092

Explanation

Returns the value of the corresponding hyperbolic function for the argument.

• HYP SIN(x) : sinh 𝑥 = (𝑒ˣ - 𝑒⁻ˣ)/2
• HYP COS(x) : cosh 𝑥 = (𝑒ˣ + 𝑒⁻ˣ)/2
• HYP TAN(x) : tanh 𝑥 = (𝑒ˣ - 𝑒⁻ˣ)/(𝑒ˣ + 𝑒⁻ˣ)

Sample Program

10  INPUT "INPUT NUMBER (UP TO 230)"; N
20  PRINT "HSN(";N;")=";HYPSIN N
30  PRINT "HCS(";N;")=";HYPCOS N
40  PRINT "HTN(";N;")=";HYPTAN N
50  END

Displays the hyperbolic functions for numeric input up to 230.
