Transcript of Discovery Nspired Proofs
What Do You Think?
• What if robot on a curved path approaches wall
• What would be modeling function for (time, dist) ordered pairs?

Ultrasonic sensor returns it's max value – "infinite" distance
Ultrasonic sensor returns it's max value – "infinite" distance
Resolving Theoretical vs. Actual
• Nspire graph using degrees• Excel graph (actual data) using time (seconds)
• But ( )f t
Challenge
• Find a non trivial set of data• Given : what is the path of
the vertex when you change the value of b?• Have the NXT robot follow a sine curve and
measure time and distance• What happens to the area of an ellipse as you
alter one of the coefficients?• What else ….. ?

Challenge
• Plot results with technology• Use same technology to analyze • Compare theoretical to actual data
• And hope it matches
