Trigonometry - Using SOHCAHTOA for Side Lengths | GCSE Maths Tutor

[@antonlawrence1022]

32 yr old here redoing maths after getting a C in 2008, never learnt trig before as sat foundation paper all those years ago. You are absolutely fantastic, thank you for all your content!

Amazing! Wishing u the best

Thank you for being able to save my maths IGCSE's! I swear, I don't know what I'd do without this channel or you

61 year old with a "U" in maths o level oh so many years ago..... clear, concise, and I can do it. Thank you!

[@TheGCSEMathsTutor]

You’ve got this!!! So glad to hear I could help 😁🙏🏼

[@dominicpartridge6075]

@@TheGCSEMathsTutor Yes, I have. I now use "trig" in my work as an Appointed Person-Lifting, writing lift plans for lifting loads with cranes. I started out of school ,with no qualifications, as a rigger and have worked my way up to the top of my game. Your method of forming the triangle really is the simplest way of remembering the equation. Thank you!

Always great to hear! Sometimes going back through a lesson in your own time after learning it in class can be super effective, getting other teachers perspectives on teaching a topic can be really powerful too! Glad to hear it’s working for you 😁🙏🏼

This has been really helpful! I've got dyspraxia, so trying to learn equations like these in the classroom is already a real chore. Combine that with a noisy class, and it's near impossible. But just watching these videos has made it almost too easy!

[@kella2007]

Hi, I just want to say thank you for these videos and thank you for making them free. I'm homeschooled and I have my IGCSEs this month. I've been really struggling with maths for the past year and a few weeks ago I found your channel. I've been going through all your GCSE videos and I understand everything so much better now. Instead of dreading the exam and not enjoying maths, I'm now way more confident and maths feels fun! Thank you so much for these videos, they are so incredibly helpful :)

[@zeinabhassan1914]

Idk how to thank you enough, but seriously Ur videos are rlly helpful and easy to understand and u work your hardest to cover any type of question that might come on that particular topic, thank you so much and Keep it up 😊

[@YN-ry6cc]

Great video Please could I request that you make a video on questions that are applicable to maths and physics by which I mean exam style questions (easy and hard) on acceleration(initial velocity and final velocity) and also questions that involve acceleration velocity(final and initial) and distance aswell. It would be really helpful to me as I am struggling at the moment

hello may i ask a question 21:59 can you for the AD length do pythagoras so 7 squared x 6.34415 squared and square root the whole thing i know its longer but i am more used to pythagoras

[@fasihanaaz9664]

Yes you can do 7 squared +6.34415 squared then square root to find AD

[@fasihanaaz9664]

7 squared - 6.34414 squared*

At 7:45 you say tan(36) is .7265 whereas my calculator says it’s 7.7504. Am I misunderstanding?

[@thunderthief7070]

tan(35) is 0.7265 so you may have inputed the value wrong

[@UnwrittenDetective_]

I got the same thing, can someone explain?

[@mailaryaarun]

@@UnwrittenDetective_ you have to change your calculator from Rad to Deg, search on KZbin how to do this.

May I ask why did you minus using the pythagoras theorem instead of adding a²+b² to get c²

[@rosie1176_]

was juuustttt tryja find out why he did this haha

[@fasihanaaz9664]

Because you’re not finding the hypotenuse (longest side) you only add using Pythagoras when your finding the hypotenuse,he was finding a shorter Side that’s why he subtracted!!

Hi! For the question at 22:54, the answer I got is 12.72cm and the correct answer is 13.1cm as shown in the video - so since there isn't much difference between my answer and the correct one, I was wondering if my answer will still be marked right or do I need to get the exact, accurate answer to get full marks? Please reply x

[@TheGCSEMathsTutor]

Make sure you aren’t rounding numbers before the finals steps, you would lose answer marks but would pick up method/process marks 😁🙏🏼

Hi, I am a bit confused by the one before last. Why can't I use Pythagoras as 7^ + 12^ = c^ and then find the square root to get the length of AC?

[@infinity8917]

yeah I was wondering too

[@willzz2122]

I’m think is because in the triangle on the right there is no degree (not including right angle) but I’m not sure so take this as you may

[@fasihanaaz9664]

Because the whole triangle ABC is not a right angled triangle,Pythagoras only works for right angled triangles
