EC-4041  (650-0820)              Features              Faxback Doc. # 3415

The Radio Shack EC-4041 Scientific Calculator is one of the most complete
and compact calculators available.  Its dual-power system lets the
calculator operate from both internal battery and solar power.

The calculator helps you solve problems in anything from basic math to
trigonometry, statistics, logarithms, and decimal/binary/octal/hexadecimal
conversions.

The EC-4041's formula entry operating system lets you enter a calculation
exactly as you would write it down on paper.  It then judges which
operation to perform first, using standard algebraic logic.  You can then
use formula replay to correct your calculation or change it to use
different numbers without having to re-enter the complete calculation.

Your calculator features:

Engineering Symbol Notation - Lets you calculate with unit symbols for
                              kilo, Mega, Giga, milli, micro, and so on.

   Complex Number Functions - Let you quickly determine the absolute value
                              and argument for a complex number and
                              perform number calculations.

          Fraction Function - Lets you input fractions without having to
                              convert them to decimal values.

     Seven Memory Registers - Hold information for later use, even after
                              you turn off the calculator.  The calculator
                              also has another' answer memory' so you can
                              use one calculation result as a part of the
                              next calculation.

       Conversion Functions - Let you convert fractions to decimals,
                              degrees/hours/minutes/seconds to decimal
                              format and back, and polar-to-rectangular
                              and rectangular-to-polar coordinates.

                Base n Math - Let you perform logical math and conversions
                              between base 2, 8, 10, and 16.

    Trigonometric Functions - Let you perform sine, cosine, tangent,
                              arcsine, arcosine, and arctangent functions
                              using either degrees, radians, or gradients
                              as the base unit.

      Logarithmic Functions - Provide quick access to log base-10 and
                              natural logarithms (base-e).

      Statistical Functions - Include both standard deviation calculations
                              and linear regression analysis calculations.

      Probability Functions - Let you quickly determine the number of
                              permutations and combinations for a set.
