hi thank u so much for this video but where can i find the rest of these questions (eg: 3.1 , 3.2 , 3.3 ) so the whole question of each graph that you have explained
Hi, hopefully you reply today! :)) Should I memorise the standard deviation equation or will it always always given in exams? Thank you! I have a whole unit 2 exam tomorrow..
@@AlevelBiologyHelp Hi, I just finished the exam 10 minutes ago and there was a standard deviation question but the equation was given! Thanks for the help though, I appreciate it. I didn't try memorising the equation anyway because I had way more to focus on. Your videos helped a ton!
So, basically a tangent is a straight line that "just touches" a curve and is used a calculate a gradient which in this case would give us the rate. They're used because it's very difficult to make accurate calculations with a curve. You can draw the tangent at any point on the curve and it can be any length because you'll get the same answer. To find the gradient (rate) it's just a case of dividing the y axis by the x axis. Hope this makes sense? :)

Very helpful video, especially in understanding the standard deviation bit. I appreciate this
could you please do videos on the required practical's(common exam q, variables) things they could ask us questions on.
Course! This week's video will be on essays but I'll do practical questions next!
Yes thank you!

Aw I'm so sorry for not replying soon enough. You don't have to memorise the equation as it isn't on the specification so you'll be given it!

hi, I dont get how to find out the tangent at 24:33 ....?
