WHAT IS CALCULUS?
MATHEMATICS OF CHANGE
•
Unchanging
•
Changing
• Force
• Steepness of incline
• Speed
• Amount of energy
MAKE IT LINEAR
WHO USES THIS STUFF?
•
Electric company
•
•
Determining length of cable between two towers
Construction
•
• Calculate area of a complicated, non spherical shape
• Cost of material, maximum force to withstand
•
•
The sensitivity of demand to changes in price varies with product.
• Light bulbs (need) vs. iPad (want)
WHO USES THIS STUFF?
•
Automobile industry
• Maximum impact on car crash to avoid head injury
(thus air bags were born)
•
Forensic Scientists
• Estimated time of death using “Newton’s Law of Cooling”
•
Musicians
• Approximate wave functions (detect tones on guitar, pianos, etc.)
REVIEW MATERIAL
LINEAR EQUATIONS
•
Equation of a line
•
Slope of a line = m
•
Y-Intercept = b
y = mx + b
rise changein y y y2  y1
m



run changein x x x2  x1
Greek “delta” symbol
