How to Graph the Cosine Graph with Multiple Transformations

Показать описание

👉 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.

Someone should show this to
My teachers so they know how to

I was confused on how the x-scale was obtained, until now. This helps soooo much.

Hi, math teacher here, really love how you have an x-scale. The curriculum we teach has no reference to this and my students will love it. Having a formula outright for an x-scale for them to use is awesome, thanks!

8 minutes and this man has taught me more than my teacher has failed to teach in 2 weeks. Thank you and this man has t

Brian you rock man, Im a 44 year-old mom of a high school senior doing credit recovery during Covid-19 at home. I have not had precal since Auburn University 1994. Thank you for running through some algebra steps, so much has changed. My son can enter the formulas into a graphing program ( desmos I think), but I pick up the formulas and rules better. I really needed to see you do the common denominators and walking through the formula. Thank you so

oh so the scale is period/4 !
I thought you meant pi/4 lol. I was going crazy getting weird numbers in the calculator.
Thank YOU I AM OFFICIALLY MCLOVINYOU!!!!

i know this video was 8 years ago but i do online school and the way you put it is so straightforward and easy to understand. i love how instead of including a whole ton of irrelevant information you just show us how to do the work and how to solve it.

the issue i have with online school is they put a ton of information in one single paragraph and it's hard to decipher what they're trying to say. i appreciate the way you explain it and give us step by step in an easy way to follow.

youve helped me a lot this year thank you a lot :-)

This helped me so much for online school. Especially when catching up to things I could not get. Thank you so much.

I just wanted to thank you for making this video because it has really helped a lot. I was so stressed for my quiz, but I remembered the way you taught how to do the phase shifts! Thank you sooo sooo much

My revision and study for my exams are much easier with your explanations. Thank you so much for dedicating time to help others, you are a hero!

This was BEYOND helpful. Thank you so much.

I was having hard time going through these trig function graphings, and this video helped A LOT! I wish you were my math teacher. Thanks so much for making this vidoe :))

I enjoy your style, you remind me of my high school math teacher (who I owe many apologies too). It's been 13 years since and I'm finally ready to listen, thank you for posting these videos!
