Final answer:
Creating the coordinate plane system, developing the scientific method, and inventing the astrolabe are all examples of mathematical innovations.
Step-by-step explanation:
Creating the coordinate plane system, developing the scientific method, and inventing the astrolabe are all examples of mathematical innovations. These achievements were significant contributions to the field of mathematics and navigational techniques. The coordinate plane system allowed mathematicians to graph equations and solve problems graphically, while the scientific method provided a systematic approach to conducting experiments and gathering data. The astrolabe was a measuring instrument used in astronomy to determine the altitude and position of celestial objects.
