How to Graph the Cosine Function with Multiple Transformations

👉 Learn how to graph a cosine function. To graph a cosine function, we first determine the amplitude (the maximum point on the graph), the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from the parent function), the vertical shift (the vertical shift from the parent function) and the x-scale (the distance between the turns and the x-intercepts). After we have obtained these features, we plot the points on the graph and graph accordingly.

these videos are so helpful! thank u!

Mr. Mclogan, how did you get a 4 in x-scale? please answer me

[planterina_abhish]

Sir can we take x scale=t/12-pi/4=0 so that we start with 3pi

[virginiagugliotti]

Why are you setting P.S to 0. I was taught to just change the sign to opposite. So in this case, the way I was taught, P.S. would actually be π/4 shifted to the to the right from the original position???

You are a great teacher but in this case I think you forgot to start at the phase shift and the graph is wrong. You might want to take a second look.

how to find an equation from the graph? (Can you plz make a video about how to find amplitude, period, vertical shift, phase shift from the graph

[sophiagascoigne]

dude u started graphing at 9pi on the right and 3pi on the left, this is confusing
