Functions 5.1 Primary and Reciprocal Trigonometric Ratios

[@ArchismanNath]

This N trick is really neat, thank you so much Ms. Havrot, I am a student from Mississauga and you are literally the BEST teacher that can easily explain these concepts so easily, I've never even heard of the N trick before but now my mind is blown. Thank you so much again! Subscribed as well.

[@mshavrotscanadianuniversit6234]

Well, thank you! Stick with me for the next few years and you will be well prepared for university ❤️ thanks for subscribing. Bring your friends 😊

Hello! I was a student with an average of 75%..I am a student at mississauga and you made me pass my last test with a 98%! I'm really glad you're helping me through this. Your notes are amazing! Would it be possible for you to photograph your notes and upload them to kami and post them in your comments somewhere so us students can view them. Thank you miss! :)

[@mshavrotscanadianuniversit6234]

So proud of you!! Yes! You can find all my class notes here: mshavrot.pbworks.com/w/page/21867096/Ms%20Havrot%27s%20Exciting%20Math%20Classes

You made all of our high school life easier! I really appreciate all the effort you’re putting in! I have a request if you could do some lessons from the ib textbook (grade 9), my sister is in need for some great help. I’d really appreciate it! Have a lovely holiday miss! :))

[@mshavrotscanadianuniversit6234]

Sorry for the late reply. I’m out of town. I don’t have that textbook. But I do have the grade ten academic lessons which might be helpful.

Wow, the way you explained everything so simply finally made me get rid of any doubts I had with the topic. Like other's have said, I loved how you encorporated the "N" trick and is definatley something I'm going to use going forward. I just want to thank you so much for this playlist as I can finally understand my Trig lessons without mindlessly flipping through the homework apendix and the messy lesson notes/packages we are given.

[@mshavrotscanadianuniversit6234]

I’m so glad that you are finding my lessons helpful! Thanks for watching. ❤️

when solving for theta, how would you proceed if instead of sin(theta)=0.624, but rather csc(theta)=0.624, thanks

[@mshavrotscanadianuniversit6234]

First you need to know that when you find a sine or cosine ratio the value will always be less than or equal to 1. This is because you are taking the ratio of the opposite or adjacent sides over the hypotenuse. Because the hypotenuse is always larger (or equal to) the adjacent or opposite sides. Example let’s say your hypotenuse has a measurement of 5 and your adjacent side is 3 and the opposite side is 4. Your ratios will be 3/5 and 4/5. Now let’s say you want to find the cosecant ratio which is hypotenuse over opposite. The ratio will be 5/4 which is greater than one. What I am pointing out is that you would never have cscθ = 0.624. Back to the how to …. Let’s say your cscθ = 1.234 to find the value for θ you would first find 1/1.234=0.81 and then you can simply use sin-1(0.81) = 54.14° (approx).

@@mshavrotscanadianuniversit6234 Ahh, yes, I see. There is just one extra step to convert it into normal form, like in the video. Thank you!

I am really struggling to remember which inverse equation (csc, sec, and cot) belong to tan, cos, and sin. Do you know a way to help memorize their connections to one another?

[@mshavrotscanadianuniversit6234]

I always told my students that long ago they used stone tablets to write on. The person in charge of writing the inverses made a mistake. Basically you would think that cos should go to cosecant and sine to secant but the person in charge messed up but it was too late. 😂 tangent to cotangent is the only one they got right.

Is there a quick review video that you suggest because I think I need one form grade 10 so I can fully understand 5.1. (Do you think I should watch some of your grade 10 trigonometry videos so I can be up to speed)

[@mshavrotscanadianuniversit6234]

Always a good idea to review. In my playlists there are all the basic grade 10 Trigonometry lessons.

Hello Ms. Havrot. Thank you so much for making these videos and making our lives so much easier. You are literally the BEST. I am struggling with questions 17 & 18 on page 264. Could you help me with those please?

[@mshavrotscanadianuniversit6234]

It would be very difficult for me to explain this other than to say that you need to do some graphing and modelling of the functions. Sorry!

[@Kristina-oh4vg]

Hi can you please do 5.1 (Pg. 282) #13, 14, 15 . It would help me out a lot!

Remember, struggling in math? Yeah , me neither

Great if that’s the truth, great if it isn’t as well, as to struggle means that you are working towards understanding. Not struggling at all could mean that you aren’t being challenged. 😊
