Thank you for a GREAT video. The link for the worksheet was expired, but I just paused a lot and drew out all 9 problems as you covered them. You got a thumbs up (wish I could give more) and I subscribed. Your explanations were very clear. I know this trig, but I don't use it enough for it to be 2nd nature. I have a Texas Inst TI36X pro, It has a 1 over function or x over x, so I don't use the X -1. Unfortunately I do not have DMS, I would have to look up the conversion. (Dont really need it though) Edit: I refreshed the old brain, the whole # is degrees, multiply the decimal by 60, that whole # is minutes, repeat for seconds.
Basic trig is one of the most useful forms of math. Should anyone forget something about it the Machinist's Handbook has almost all of it. Being a glutton for punishment I took enough calculus to get a minor in math but haven't used it since college. On the other hand I've used trig quite often. I tutored math while spending long months at sea. Sometimes I wasn't a very good teacher because I had a few guys that just couldn't understand.
Could you imagine living in a town & only knowing how to get to main st. one way? This video really is for beginners. Hope you all get past this very soon...
My Apple I-phone 11 does not have the X1- key. Also, I have to hit 30-sin x 5. It doesn't work if I hit sin-30-x-5. I guess I'll have to buy a calculator to do Trig.
This comment is for anyone else having this problem as I'm sure you have figured this out by now. To get the Sin-1, you first hit the (2nd) button. Sin, Cos & Tan will now have the -1.
This was a great video and teaching.... However, I do not have a scientific calculator. The one that is one this PC does the trig function differently as to how to type it in... no problem until you get to getting the angles! Then can't figure out what combination of buttons to hit. Nothing I tried came up to the correct angle! I have to get a good sci calculator!!!
The calculator you have will probably do the exact same thing If you’re using a computer you could always download the sharp calculator app This year being online I had my students download the app that way we all have the same calculator Hope this helps Ray
@@shopandmath cheers I have a new desire to learn maths having struggled with it at school. People like yourself taking the time to teach this stuff on line are greatly appreciated by me.
@@thornwarbler Thank you for the very nice comment Positive comments is gas in the tank to help me make more videos Thank you for taking the time to comment it’s much appreciated Ray
@@twistedhairball yes there are 3 more parts to come law of sine law of cosine and law of cotangent (not in most books ) this might take a while to be posted Ray
I’m guessing that you’re from a country that doesn’t use imperial or inch which is most of the world Metric is written in the form of decimal degrees Inch or imperial is a little bit more complex it is written as degrees minutes seconds Every degree has 60 minutes in it And every minute has 60 seconds in it A simple example would be metric 0.5° equals inch 30 minutes I understand that this could be a little bit confusing it’s more of a video answers that are written answer I hope this helps you Thank you for commenting Ray
So very clear and concise. This is great thank you
So clear and easy to understand. Thank you so much !!
I’m glad that you enjoyed the video
Thank you for leaving such a nice comment and thank you for taking the time to comment. It is much appreciated.
Ray,
I enjoyed this video and others so much, I pasted the URL for this video on my forum of 31,000 members.
Thank you for your outstanding videos!
post a link to the forum
Great video & easy to learn from! Thanks!
I really liked the video. I am a beginner and you made me a pro. Thank you!
thank you
for the comment
its nice to get positive ones

there are some great apps but students can not use them or there phone during tests

hi Jeff dont buy a calculator unless you are in a class
try the app trig solver I made a video about it "shop tools tips and tricks 2"

If you want a calculator, walmart has a Texas Instruments (TI-30XllS) for around $12. It has way more than you'll need at a good price.
On the last three problems, why use the DMS function to find the angle rather than just use the inverse trigonometric functions?
Thank you for this.

You might want to correct the misspelling in the thumbnail.
nice one
unfortunately once its in the video I can not edit it out :-)
Nice video I enjoyed it. I also make educational videos too.
maybe we can do a collaboration video together
@@shopandmath yea I really love that idea
So how do we start
@@prospect_fx1 come up with an idea and email me shopandmath@gmail.com
ray
@@shopandmath you can start up by subscribing to my channel
Amazing!
Thank you! Cheers!
This is great, thanks a lot!!!
I am glad that you liked this
Ray
@@shopandmath will you be doing a part 2? I know so little about it I don't even know what else I don't know :)
@@twistedhairball
yes there are 3 more parts to come
law of sine
law of cosine
and law of cotangent (not in most books )
this might take a while to be posted

@@shopandmath awesome ill keep my eye out!!! Thanks for replying Ray
👍
9:10
1/Sin(30) X 5 = 10
After all, Csc is 1/Sin
just type it in that way.
5/Sin(30) = 10
For number 7 what did the angle equal and what didthe adjacent equal
36.87°, it is also 36° 52' (minutes) 12" (seconds).
Adjacent is 4
What does the minutes and seconds mean?
I’m guessing that you’re from a country that doesn’t use imperial or inch which is most of the world
Metric is written in the form of decimal degrees
Inch or imperial is a little bit more complex it is written as degrees minutes seconds
Every degree has 60 minutes in it
And every minute has 60 seconds in it
A simple example would be metric 0.5° equals inch 30 minutes
I understand that this could be a little bit confusing it’s more of a video answers that are written answer
I hope this helps you
Thank you for commenting
Ray
@@shopandmath Thank You!
How can I download the problems?
In the description below there’s a link to download the handout
link for material has expired :)
its fixed
Ray
Exaples? Or examples?
You get both
9 "Exaples"
Lost me there, not worth the time if you can't get that right.
Thank you for taking the time to comment

It’s for Trig, not spelling,,,,lol
