Scientific Calculator User Guide.
The candidate is allowed to use the calculator at any time during the exam.
The Basic calculator performs fundamental calculations:
MC: Memory Clear, clears calculator memory, clears all, and starts a new operation.
MR: Memory Recall, displays the memory value.
M+: Memory Plus, add displayed value to memory.
M-: Memory Minus, subtract displayed value from memory. Note: On a scientific calculator a value is stored as a positive number into a negative number, usually marked (-) or NEG (negation).
MS: Memory Store, stores a value to memory.
( ): Parentheses, denote the order of operations.
Numeric from 0 to 9.
÷: Divided by, over, division by.
DEL: Removes a single character or digit from the current input.
X: Times, or multiply by.
C: Clear, clears the current display value.
-: Minus or subtraction.
√: Square root, Calculates the square root of the value.
+: Plus or addition.
=: Equal to, finds the result of an operation.
.: Decimal, enters a decimal point.
In addition to the basic calculator function, the Scientific calculator is of two types, Type1 and Type2.
Type1 of the Scientific calculator:
%: Percent, calculates the percentage of a value.
x²: Squares the value, square the displayed value and displays it.
x3: Cubes the value.
xy: x raised to the power y, calculates exponential values.
ex: Exponent, raise e to the power x. Calculates powers based on the constant e (2.718281828).
2x: Base 2 exponential value.
1/x: Multiplicative inverse or reciprocal for a number x.
2√x: Square root, calculates the square root of the value.
3√x: Cube root (of) x, calculates the cube root of the value.
ypx: yth root (of) x.
ln: Log to the base of e, the natural logarithm of a value or expression. Computes the value of the natural logarithm, the exponent of the power to which e must be raised to equal the given value.
lg: Inverse function of exponential function for a positive real value.
x!: The product of a given positive integer x multiplied by all the lesser positive integers from 1 to x-1 is indicated by x! and called the factorial of x.
sin: Sine of a value or expression.
cos: Cosine of a value or expression.
tan: Tangent of a value or expression.
e: Base for the natural logarithm.
EE: Enter Exponent, enter the numbers with exponents of 10.
Rad: Convert degrees to radians, Radian is default.
sinh: Hyperbolic inverse sine (arcsine) of a value or expression.
cosh: Hyperbolic inverse cosine (arccos) of a value or expression.
tanh: Hyperbolic inverse tangent (arctangent) of a value or expression.
tan-1: Inverse tangent function.
π: Pi, display the value of π as 3.141592654 to use in a calculation.
Rnd: Round to the nearest integer.
Type2 of the Scientific calculator:
yx: y raised to the power x.
logy: Log to the base y.
log2: Binary logarithm.
sin-1: Inverse sine function, arcsine.
cos-1: Inverse cosine function, arccosine.
tan-1: Inverse tangent function or arctangent.
sinh-1: Hyperbolic inverse sine (arcsine) of a value or expression.
cosh-1: Hyperbolic inverse cosine (arccos) of a value or expression.
tanh-1: Hyperbolic inverse tangent (arctangent) of a value or expression.
