RPN Engineering Calculator $39.00
This RPN calculator offers a choice of more than 200 solutions with five unique keypads. It has a complete help system with individual tips for all but the most ordinary functions. You can choose between fixed, scientific and engineering notation and select degrees or radians as required. You can print the contents of the running tape display. The functions available using any keypad are, Lastx, retrieves the last number that was used in a calculation, Drop, deletes the current value in the x-reg and Drops the number in the y-reg into the x-reg, x<>y, exchanges the values in the x-reg and y-reg, STO, which can save up to 4 numbers into memory (the "m" key), x^2, square root of x, 1/x, and 8 constants involving pi. Standard. Engineering and Trig keypads also have a convenient function to convert between polar and rectangular coordinates. Briefly, unique to the 5 keypads are: Standard – contains several of the functions found on a normal scientific calculator (log, ln, N!, etc.), and some unique to itself: Compound interest and sales tax calculator, statistics, a simple math teaching aid for kids, and more. Engineering – handles problems like Resonant Frequency, Ohms Law, Parallel Complex Impedances, Filter Response, Polynomial Equations, Impedance of a Ladder Network, a series, and a parallel resonant circuit, and more. Magnetics – eases the design of transformers and inductors with many built in functions unique to magnetic component design. Engr'g and Mag. now offer selecting units used in many of the calculations. Trig – solves Arc Length, Right Triangle, and any Defined Plane Triangle problems. Computes sine, cosine, tangents, secants, cosecants, and cotangents, and their inverse, as well as hyperbolic sine, cosine, and tangents. Converts Radians to Degrees, and Hours, Minutes, Seconds to Decimal Hours and vice versa. Convert – thousands of conversion possibilities including converting between decimal and binary, octal, or hexadecimal numbers.
