You could but it was pretty easy to sketch without the mapping rule. Depends on what your teacher asks for. If it's just a sketch they are asking for then you don't need to use the mapping rule. If you are asking about 8a) I did use the mapping rule at the end.
k affects the period of the function. So, basically all you have to do is divide 2π by k and you have the period. Remember then to divide the new period by 4 to get the four intervals for one period.
This is more of like a grade 11 function standard I would say, In my school we go much deeper than this in grade 12. but still it's a great review for trigonometry.
You can do it two ways. If you are only asked to graph it, you should be able to adjust the period, amplitude, shift etc directly onto the graph remembering that the sine or cosine graph divides very nicely into quarters. Otherwise you CAN use a mapping rule and use the key points of the original function ... for sine, you would use (0,0), (π/2, 1), (π, 0), (3π/2, -1) (2π, 0) then apply your mapping rule to find the points.
I did questions from the textbook but im not getting it right like the textbook it was questions 6a.b.c.d and here is how i did it. file:///C:/Users/User/Downloads/CamScanner%2010-27-2021%2010.10%20(2).pdf. What am I doing wrong, I followed the steps and i did it the longer way because it is easier to understand
GIRL YOU ARE A QUEEN THANK YOU SO MUCH FOR YOUR HELP APPRECIATE YOU EVERY DAY !!!
Thank you for the sweet comment ❤️
Happy that you are enjoying my lessons.

hi ms, why didn't you use mapping rule for the second question?

How would you input the k transformation on the graph?

what school did u go 2
Wonderful presentation; thank you for sharing.
You’re most welcome! 🤗
Thank you so much! This is amazing and your lessons have been helping me a lot! I’m eternally grateful!
Thanks for watching and I’m happy that I have been able to help you with your lessons 😊

How can I make sure I get points between -2pi to 2pi. My teacher won't let my graph go over 2pi
You can always erase !
Also once you know what the period is you may need to plug in some other points in the domain.
just wondering about the mapping rule for the first example you did, why would it be + pi/6 rather than - pi/6 since the pi/6 is negative
Remember it’s minus minus here! (From the formula) That’s why it becomes positive.
How to you input the transformations on the function sine and cosine?
