Errors in this video:

At the 5:07 mark he says the y-coordinate on the max is 0, but it is actually 1. At the 5:24 mark, he says the y=coordinate on the min in 0, but it is actually -1.

Lesson Summary:

In this lesson, we learn how to graph a sine function with a transformation, specifically a vertical and horizontal shift. Using the formula for the amplitude and period, we graph the parent function before applying the transformation. It's important to be careful with the placement of the y-axis, as the horizontal shift can be either left or right. Finally, we find the key points, including intercepts and min/max values, to complete the graph. Understanding how to graph sine functions with transformations allows for a deeper understanding of trigonometry and its applications.

Graphing a sine function with a transformation

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.

    The instuctor shows how to graph one period of the sine curve and then perform a horizontal shift on the graph. He also shows the equation of the shifted graph.
