## Calculus – Find the Definite Integral of a Trigonometric Function

## Calculus – Find the Definite Integral of a Trigonometric Function – Example 2

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

## Calculus – Limits Indeterminate Form

Limits Indeterminate Form In this tutorial students learn how to evaluate the limit of a function when direct substitution results in the indeterminate form of infinity times 0. Rewrite the function so that a different indeterminate form is created and then L’hopital’s Rule can be applied. Virginia Standards of Learning(SOL) APC.2, APC.8

## Math Analysis – Polar Coordinates Basics

## Math Analysis – Angle Between Vectors

## Math Analysis – Average rate of change of a trigonometric function

Average rate of change of a trigonometric function In this tutorial students learn how to evaluate the average rate of change of a trigonometric function over a specified interval. Virginia Standards of Learning(SOL) SOL APC.6 The student will investigate the derivative at a point on a curve. This will include a) finding the slope of a curve… Read More »

## Trigonometry – Unit Circle Construction – COUNTING METHOD

Unit Circle Construction – COUNTING METHOD In this tutorial students learn how to create the Unit Circle based off of memorization. Virginia Standards of Learning (SOL) T.1, T.2, T.3 Notice how all of the (x,y) values have a denominator of 2. Notice the 1, 2, and 3 counting technique used for each of the numerators. Take the square… Read More »

## Trigonometry – Unit Circle construction from scratch

Unit Circle construction from scratch In this tutorial students learn how to create the Unit Circle based on knowledge of the 30,60,90 and 45,45,90 special triangle and fact that x=cos(theta) and y=sin(theta). Virginia Standards of Learning (SOL) T.1, T.2, T.3 Notice how all of the (x,y) values have a denominator of 2. Notice the 1, 2, and 3… Read More »
