Graphing Linear Equations on a Graphing Calculator

00:00

Graphing Calculator Lesson (TI-84)

Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.

Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = –3x and the circle x² + y² = 3.

Numerically Calculate the Derivative of a Function

00:00

Graphing Calculator Lesson (TI-84)

Calculating the derivatives of a function on a graphing calculator.

Calculating Maximums/Minimums from a Graph of a Function

00:00

Graphing Calculator Lesson (TI-84)

Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines.

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.

Numerically Calculate the Value of a Definite Integral

00:00

Graphing Calculator Lesson (TI-84)

Taught on a graphing calculator, this lesson is how to Numerically Calculate the Value of a Definite Integral in calculus.

Trig Functions using the Graphing Calculator

00:00

Graphing Calculator Lesson (TI-84)

Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle.

Absolute Value - on a Graphing Calculator

00:00

Graphing Calculator Lesson (TI-84)

Graph square root, cube root, and piecewise-defined functions, including step functions and absolute value functions.

Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.

Logarithms Using the Graphing Calculator

00:00

Graphing Calculator Lesson (TI-84)

Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude.

For exponential models, express as a logarithm the solution to ab​(ct) = d where a,c,and d are numbers and the base b is 2,10, or e; evaluate the logarithm using technology.

Calculating a Value on the Graph of a Function

00:00

Graphing Calculator Lesson (TI-84)

Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function.  Read values of an inverse function from a graph or a table, given that the function has an inverse.
