• Mathematical Functions:
SIN(X) : sine of x
COS(X) : cosine of x
TAN(X) : tangent of x
COT(X) : cotangent of x
ASIN(X) : arcsine of x
ACOS(X) : arccosine of x
ATAN(X) : arctangent of x
SINH(X) : hyperbolic sine
COSH(X) : hyperbolic cosine
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
ABS(X) : absolute value of x
FCT(X) : x factorial
LOG(X,Y) : logarithm of y to base x
LN(X) : natural logarithm of x
LOG(X) : base-10 logarithm of x
LOG10(X) : base-10 logarithm of x
LOG2(X) : base-2 logarithm of x
EXP(X) : base-e exponential of x
ERF(X) : the error function of x
ERFC(X) : the complementary error function of x
ROUND(X) : integral nearest to x
CEIL(X) : the smallest integral that is not less than x
FLOOR(X) : the largest integral that is not greater than x
TGAMMA(X) : the gamma function of x
LGAMMA(X) : the natural logarithm of the absolute value of the gamma function of x
X^Y : y-th power 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}
