Computes transcendental functions 10 times faster than a slide rule. For greater speed and versatility, the following specific functions are preprogrammed into the HP 35:
- Arithmetic: Add, subtract, multiply, divide and square root.
- Trigonometric: Sine, arc sine, cosine, arc cosine, tangent and arc tangent.
- Logarithmic: Common logarithm, natural logarithm, natural antilogarithm.
- Other functions: xy, 1/x,, data storage and positioning keys.
Easy-to-read LED display gives answers with accuracy of up to 10 significant digits. Decimal point is automatically positioned. Numbers smaller than 10-2 and larger than 1010 are displayed in scientific notation, with the exponent of 10 (phis or minus) shown at the extreme right.
Pre-programmed functions let you perform log, trig and exponential calculations 10 times faster than with a slide rule.
Operates on battery or AC-line power. The HP-35 comes with a rechargeable nickel-cadmium battery pack which provides enough power for three to five hours of continuous operation. Impending battery depletion is indicated by the lighting of all decimal points in the display.
AC-line operation (115 or 230 volts) and simultaneous battery charging are accomplished by simply plugging in the battery charger supplied with the HP-35.
Compact, rugged case fits easily into shirt pocket or briefcase. Four-register, operational memory-stack automatically Stores and retrieves intermediate solutions during complex calculations, eliminates need for scratch notes and re-entry of data. Data manipulation keys allow contents of any register to be displayed for review. A separate, addressable memory register is also provided for storage and retrieval of constants.
