Nancy plsss come back teach us moree ur the best teacher

Thank you for making this so simple and clear, I barely made it out of college algebra and now find that I need a solid base of trig for development. You definitely have the gift of teaching, again thank you for sharing...

So calmly expressed with a soft teaching voice that enables one to grasp. Thanx and much appreciated Nancy!

If anyone is wondering what the functions actually are, rather than just how to to calculate them, they're ratios. For example, 5/10 = 0.5 is essentially saying that 5 makes up 50% of 10. Likewise, for SIN as an example, it's basically saying the Opposite makes up result% of the Hypotenuse. In her example of sin, Nancy has it equal to 4/5. This means that the length of the opposite makes up 80% of the length of the Hypotenuse. This of course applies for all the trig functions. If you want to know what they're used for, Nancy did another awesome video explaining it here: kzread.info/dash/bejne/k2mLs86cdre-qc4.html

Thank you for the review. Haven't seen much trigonometry since I retired as an optometry professor 12 years ago. Very good effort and easy to understand.

This really really helped me understand it! Thanks so much! Your pace at which you go is perfect because it allows me to take my time in understanding the material.

Brilliant! Very easy to follow - Clear and Precise speech - Nice steady pace - perfect simplicity - I have confidence in this subject in less than 15 minutes - THANKS Nancy XX

Thank you so much!! I barely got through algebra in college and have only used basic arithmetic since then. Now that I'm retired, I am determined to learn the fundamentals of trigonometry so I can finally understand how, after "shooting the stars" with a sextant, accurate timepiece, and various navigational publications, my fellow quartermasters and I were able to find our ship's position on the high seas. I appreciate your calm, unhurried teaching style and will be watching all of your videos. Thanks again!!

Amazing explanation. I saw this crop up in a programming example. It was an animation of the Earth circling the Sun. In the code it used sin and cos to determine where to draw the Earth. I didn't know anything about it so I searched and found your video. Really cleared it up for me. Thanks!

During 1990, i spent so much time trying to understand this because although i was told how to use Sin cos tan etc but then i didnt know if sin represent an specific angle with refrence to the right angle or is this ratio of angles. My teacher unfortunately was not intrested in teaching during the regular classes at school as much as he would teach at his home for a tuition fee. Today this small video gave me the answer. Namaste 🙏 .

She’s writing backwards on a clear surface… You can tell because her body is not blocking the text when she overlaps it. Left-handed people don’t write in a direction that goes away from their bodies, unless they’re writing backwards. If she is right handed her hand should be covering the text as she writes.

@solarfluxman8810

5 жыл бұрын

@@Lanefasts - Yes, she is behind a clear screen. But, she is not writing backwards, that would be quite difficult at the speed she writes, and it would not be pretty. She is right handed, writing behind a screen in a normal manner with her hand moving away from her as she writes. She is not blocking the text with her hand, because she is behind the screen. But, looking at her from our side of the screen, the writing would normally appear backwards. So the solution is to either place a mirror between the camera and the screen to reverse the image, or to simply reverse the left to right orientation in video editing. That's why it looks like she is using her left hand. Try it at home. It's easy to do. Just use a mirror when recording the video. My apologies to Nancy, if you were trying to keep this a secret mystery. I know you probably don't want everybody to copy your clever presentation style.

Oh. My. God! Welcome Back Nancy!

I want to thank you for bringing up those different kinds of right triangles because the third one you drew use to make it difficult for me to understand what title was what but you cleared that up perfectly.
