Calculus in 10 Minutes or Less. Slope. p osition. time. Slope. p osition. tangent!. time. Derivatives. Derivatives are the slope of a function at a point Slope of x vs. t velocity - describes how position changes over time Slope of v vs. t
E N D
Slope position time
Slope position tangent! time
Derivatives • Derivatives are the slope of a function at a point • Slope of x vs. t • velocity - describes how position changes over time • Slope of v vs. t • acceleration - describes how velocity changes over time • Slope of a vs. t • jerk - describes how acceleration changes over time
If the position of an object is described by the function What are the velocity and acceleration functions?
Area velocity Easy! time
Area velocity Harder!!! time
Integrals • Integrals are anti-derivatives • Graphically, integrals are the area under a curve • Area under a v vs. t graph = Displacement
An object’s acceleration is described by a(t) = 2t. Find the velocity and position functions.
Initial Conditions If x = 5 when t = 0, what is the displacement function for this velocity function? -so- -so-
Definite Integrals • Taking the integral from one point to another. • Same rules apply, but don’t have to do “+C”
Find the displacement from t = 2 seconds to t = 4 seconds for the velocity function
