At time t=2, the velocity of the particle is 2. What is the velocity at time t=3? </video> <video> Calculus 1.2f - Derivative from Given Data Description: Approximating a derivative given a table of values. The rate of change of a function at a given point can be approximated from given data points even if the equation of the curve is not known. </video> <video> Calculus 6.08m - Examples 16 - 17 Description: Two more examples of limits that can be evaluated using L'Hopital's Rule </video> <video> Calculus 1.2a - Position and Velocity Description: The beginning of the introduction to derivatives, using the example of position and velocity. These concepts of motion were some of the questions that originally motivated Isaac Newton to formulate the theory of derivatives. Position and velocity are discussed graphically and the slope calculation is shown. </video> <video> Calculus 6.08k - Limit of 1+1 over x to the x Description: Using L'Hopital's Rule to evaluation the limit of 1 + 1/x to the power or x, and some comments on the familiar final result. </video> <video> Algebra 2 7.4p3 - Practice Problems 3 - 4 Description: f(x) = 3 log_4(x). Find the inverse of function f. f(x) = ln(x+7) / 2. Find the inverse of function f </video> <video> Calculus 6.08l - Examples 13 - 15 Description: L'Hopital's Rule. Three examples of limits that can be evaluated using L'Hopital's Rule. </video> <video> Calculus 1.2b - Interpreting a Graph Description: Interpreting a graph of position vs. time, and using the graph to answer questions about rate of change </video> <video> Geometry - Exam 2 Review Problem 14-06 Description: Geometry second semester exam review. A circle fits inside an isosceles trapezoid as shown. Find the area of the shaded region. </video> <video> Calculus 1.2c - Average and Instantaneous Velocity Description: The concepts of average velocity and instantaneous velocity are explained and are used to introduce the concept of the derivative at a point. </video> <video> Geometry - Exam 2 Review Problem 12-11 Description: Geometry second semester exam review problem. Circle C is inscribed in triangle PQR as shown. PR = 1.8 QR = 2.4 PQ = 3.0 a) Is PQR a right triangle? b) What type of shape is FCER? How do you know? c) Find the radius of the circle. </video> <video> Calculus 1.2e - Derivative from an Equation Description: Approximating the rate of change at a point when given the equation for a graph. An approximation is done using a forward difference quotient, and the advantages of using a small interval and a symmetric difference quotient are discussed. </video> <video> Calculus 1.2d - Derivative from a Graph Description: Using a tangent line on a graph to estimate a derivative. Using a graph of position vs. time, the average velocity and the instantaneous velocity are both considered. The technique of finding the slope from a tangent line is demonstrated. </video> <video> Algebra 2 7.4p4 - Practice Problems 5 - 6 Description: f(x) = e^(1.4x - 2). Find the inverse of function f. f(x) = 3e^(5x) + 1. Find the inverses of function f. </video>
