TANH(X) : hyperbolic tangent
ASINH(X) : inverse hyperbolic sine
ACOSH(X) : inverse hyperbolic cosine
ATANH(X) : inverse hyperbolic tangent
SQRT(X) : square root of x

• Statistical functions:

SUM(a1,a2,a3,a4) : a1+a2+a3+a4
AVERAGE(a1,a2,a3,a4) : (a1+a2+a3+a4)÷4
VARIANCE(a1,a2,a3,a4) : variance
SD(...) : standard deviation
SUMSQ(...) : sum of squares
AD(...) : absolute deviation
CV(...) : coefficient of variation
SVARIANCE(...) : sample variance
SSD(...) : sample standard deviation
SCV(...) : sample coefficient of variance

• Help Manual:

“//” means a line comment or annotation.

A=2
B=3
C=A+B

Click “Run”, the screen shows:

C=5

If the line C=A+B is annotated ,

A=2
B=3
//C=A+B

Click “Run”, the screen shows:

B=3

- Variable Naming Rules:
Start with letters, and not involving keywords.
A, A1, B25, HAT (right)
PRINT1, COS (wrong)

- The Usage of PRINT:

A=10+5
B=10/5
PRITN A,B

Click “Run”, the screen shows:

A=15
B=2

Default variable name is RESULT , e.g.

16+5*6

Click “Run”, the screen shows:

RESULT=46

- Combination & Arrangement:

C(n,k) = n!/(k!(n-k)!)
A(n,k) = n!/(n-k)!

- Complex Number
When there is “i” or “∠” on the screen, it automatically enters Complex Number Calculation Mode.

e.g. X=3+4i or X=5∠53.1°

9 functions are available for the Mode.
SIN(X), COS(X), TAN(X)
COT(X), SINH(X), COSH(X)
SQRT(X), ABS(X), CONJUGATE(X)

- Integral

INTEGRAL X²,2,4

Default precision is 300 times of calculations. It can be more accurate, e.g. 500 times.

INTEGRAL X²,2,4,500

- Graphics

PLOT SIN(X)
PLOT X²

Default length = 10, width = 10. Specify the lenght = 20, width = 5. Then we have,

PLOT X²,20,5

Default dense is 150 points. It also can be customized, e.g. 200 points.

PLOT X²,20,5,200
