Before smartphones, how did pocket calculators from the 1970s manage to perform scientific math, tackling complex equations with ease? This video dives into the groundbreaking technology that transformed how engineers and students approached numbers decades ago.
Discover the ingenious methods behind these revolutionary devices:
► They used specialized microchips with pre-programmed algorithms for functions like logarithms and trigonometry.
► The CORDIC algorithm was key, breaking down complex functions into simple operations like additions and bit shifts.
► Other techniques, such as Taylor series expansions and lookup tables, handled functions like exponentials and logarithms.
► Engineers painstakingly designed dedicated hardware on integrated circuits, optimizing for cost and size.
► This innovation democratized higher mathematics, allowing advanced calculations outside of mainframes and specialized labs.
