Question

which mathematical concepts were the result of the work of rené descartes? check all that apply.
theory of an earth - centered universe
formula for the slope of a line
pythagorean theorem for a right triangle
problem solving by solving simpler parts first
cartesian plane for graphing
trusting previous teachers for knowledge

Explanation:

• The Earth-centered universe theory predates Descartes and is astronomical, not his work.
• The slope formula was developed after Descartes.
• The Pythagorean theorem is ancient, not from Descartes.
• Descartes promoted breaking problems into simpler parts as a core problem-solving method.
• The Cartesian plane (named for Descartes) is his key mathematical contribution, uniting algebra and geometry.
• Trusting prior teachers is not a concept from his work.

Answer:

• problem solving by solving simpler parts first
• Cartesian plane for graphing
