The Origins of Calculus
I Who are the two people credited with the origination ofcalculus?
Hint: Gravity
Newton and Leibniz!
I Why?Algebra wasn’t enough!
I Can algebra describe:
1. Planetary motion?
2. Area under a nonlinear curve?
3. Oscillation?
What’s the point?
Mathematics has always had a purpose.
