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?

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.

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

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

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

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
