      @@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!

    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 :)
