SUMMARY

The discussion focuses on calculating the rate of change of the distance between the origin and a moving point on the curve defined by the equation y = x² + 1, given that dx/dt = 2 cm/s. The distance formula from the origin to a point (x, y) is derived as d = √(x² + y²), which simplifies to d² = x² + (x² + 1)². By applying implicit differentiation and substituting dx/dt, participants can find the rate of change of distance with respect to time.

PREREQUISITES
  • Understanding of calculus, specifically differentiation
  • Familiarity with the distance formula in a Cartesian coordinate system
  • Knowledge of implicit differentiation techniques
  • Basic understanding of the function y = x² + 1
NEXT STEPS
  • Study implicit differentiation in calculus
  • Learn how to apply the distance formula in two dimensions
  • Explore related rates problems in calculus
  • Investigate the geometric interpretation of derivatives
USEFUL FOR

Students studying calculus, educators teaching related rates, and anyone interested in applying mathematical concepts to real-world motion problems.

"Find the rate of chage of the distance between the origin and the moving point on the graph of y=x^2+1 if dx/dt=2 centimeters per second."...im sure it is a simple problem...any help?

You'll get more response if you describe what you've tried or what you are thinking.
 
What IS the distance between the origin and any point (x,y)?

What is the distance if the point lies on the curve y= x2+ 1?

Hint: In problems with distances, it is often simpler to work with "distance2" than with distance itself!
