👉 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!

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.

@planterina_abhish 6 лет назад

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

@brianmclogan 6 лет назад

yes

@chikahantime6166 5 лет назад

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

@brianmclogan 5 лет назад

period divided by 4

@lijarahman7566 5 лет назад

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 plzzzzzzzzzzzz)

@virginiagugliotti4585 3 года назад

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???

@harshdeep4all 2 года назад

because period is not 2pi as the sine graph is in the form asin(bx+c) ( it has a b (1/12) in it which alters the P.S). For all cases, you set bx + c = 0 to find P.S.

@sophiagascoigne380 5 лет назад

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

nice video

I'm taking pre calculus. I'm a senior at Oakdale High at California. Just reviewing for our test. Cool that you make videos with students and asking them questions. This 2013 Tho lol. So cool I got first comment and reply from a teacher
