Nice methods . Can we differentiate to find m for another method
@rostymaths2 ай бұрын
We can differentiate indeed. However, not at GCSE level. That would be something you do in further maths or A-Levels
@jonerasmus93992 ай бұрын
Sir is there there a difference between IGCSE and GCSE . I'm writing IGCSE exam and I bought a book that actually taught differentiation so thats was why i was wondering why you used a different method . I agree that differentiation is more a AS and A level topic but some IGCSE text books teach it hehe ! And I'm not talking about core either . When I mean IGCSE I mean on Higher/Extended . Anyways good content , good vibes .Cheers

@@jonerasmus9399 there is a difference indeed. At GCSE level, we won’t cover differentiation. There are a lot of overlap between IGCSE though. Thanks for checking.

What if you are given a gradient (start and ending gradient values) and need to find a curve that will pass through both at a tangent?
@rostymaths2 ай бұрын
Nope. That would just be an average over a period of time.

@zoltanpetofi29645 ай бұрын
this has not much to do with math at all. drawing random lines is everything but math. this is only pure speculation, why you drew exactly this line? because you already knew it has to be 4 from calculus. what if x=0,5? the real mathematic way would have been to show that the gradient of the tangent equals the value of the derivative at the tangent point. since the derivetive is 2x+2, it is pretty easy to come to the real solution of 4 if x=1 and to the other real solution of -4 when x=-3. Moreover what you wrote as two differnt methods of calculating the gradient are the same since x2-x1 is exactly delta x and y2-y1 is delta y. the first method is only the special case for the common understanding of gradient, which is: how much to go vertically if i go 1 horizontally. method 2 is the generic one for any random points.

Not everything needs to be complicated + there are tons of other more ‘advanced’ math videos you can check out if you’re not satisfied with this.

Great explanation and excellent method. Unfortunately, this is not appropriate for GCSE students. They have to do it the way I demonstrated it. Your method is what I would normally do 😉

Thank you!! I can't even put to words how much of a life saver this video is right now. I've gone back to school this year as an adult, math has never been my strong suit but you've explained this so well for me! I'll be definitely be subscribing and coming back in the future when I get stuck again.

what if there's an equation like 2m - 1 = n 4n + m = 8 what im trying to point out is that the equations aren't in an order where they are above eachother

Why didn’t you simply differentiate the quad to yield dy/dx=2x+2, then plug in x=1 or -3 to produce dy/dx=4 and -4, respectively. This exercise takes half a minute and is precise. SMH
@osumanuabubakar95575 ай бұрын
The question didn't ask you to differentiate. Specifically, the question asked you to find the gradient at given x coordinates. It requires you to be practical. Thank you
@The_ATF_5 ай бұрын
Because it’s easier to just draw a tangent in this case SMH
@jackbertholet51225 ай бұрын
If you know the equation of the parabola it is way more practical to just differentiate instead of having to draw a tangent which may introduce error. But I think this video was aimed for middle school students who are not required to know anything about calculus@@osumanuabubakar9557

How do you know when the signs are different or same
@rostymaths6 ай бұрын
Check what comes before each term. Like + or -. If they are the same, you subtract but if they are different, you add
@shaheerx7 ай бұрын
Sure! Drawing a tangent on a curve and finding its gradient involves a few steps: 1. **Select a Point:** Choose a point on the curve where you want to find the tangent. This will be the starting point for your tangent line. 2. **Draw a Line:** Draw a straight line that touches the curve at the chosen point. This is your tangent line. 3. **Find the Gradient:** To find the gradient (slope) of the tangent, you can use the formula: \[ \text{Gradient} = \frac{\text{Change in } y}{\text{Change in } x} \] Calculate the change in \(y\) and \(x\) between two points on the tangent line. The ratio of these changes gives you the gradient. Remember, the tangent represents the slope of the curve at that specific point. If you have a specific curve or point in mind, I can provide more tailored guidance!❤

Do you a video on how to add an ingredient to the whole recipe? I would have to multiply the weight by the ingredient right ? (0.25% max use level) so I would do (total weight)500g x 0.25%= 125g I would need to use 125g of one ingredient to this whole recipe. Is this right or wrong please correct me or send link to video that explains this
