Find the Definite Integral of a Trigonometric Function In this tutorial students learn how to evaluate the definite integral of a trigonometric function. The students will also verify the results on a TI-84 Plus C graphing calculator. Also note that sine is an odd function meaning … sin(-x) = -sin(x) Virginia Standards of Learning(SOL) APC.11
Definite Integral of a Quadratic Function In this tutorial students learn how to evaluate the definite integral of a quadratic function. The students will also learn how to verify the results on a TI-84 Plus C graphing calculator. Virginia Standards of Learning(SOL) APC.11 The student will find antiderivatives directly from derivatives of basic functions and by substitution… Read More »
Prime Factorization, GCF & LCM In this tutorial students learn how to find the Greatest Common Factor (GCF) and Least Common Multiple (LCM) using Prime Factorization. Students will also used the TI-84 to verify our results. Sometime GFC is also referred to as GCD, Greatest Common Divisor. Virginia Standards of Learning(SOL) SOL 4.5 The student will… Read More »
Graphing Quadratic Equations In this tutorial students will learn about graphing quadratic equations on a TI-84 Plus C graphing calculator. A quadratic equation is a second degree polynomial. The largest exponent in a quadratic equation is 2. When graphed a quadratic equation forms a parabola. A parabola has several distinct parts named the focus, vertex, axis of symmetry and directrix.
Find the vertex of the quadratic equation In this tutorial students learn how to find the vertex of a quadratic equation (parabola) using various methods. Those methods include graphing with the TI 84 C, calculus, and algebra methods like completing the square. When using the calculator I could have also used the MINIMUM function. 2ND |… Read More »
