Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

2. Consider a tangent of the curve \ (y=17-2x^2\) that goes through the point \ ( (3,1)\text {.}\) Provide a diagram of this situation. Can you draw two tangent lines? Find the slopes of those tangent ...

Find an expression for \ (m\) and \ (b\) (as functions of \ (x_1\)) such that the equation of the line \ (y=mx+b\) is tangent to the curve \ (y=f (x)\) at \ ( (x_1,f (x_1))\text {.}\) ...

Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with Bitesize GCSE Maths Edexcel.

Find the equation of the line of symmetry and the coordinates of the turning point of the graph of y = x 2 6 x + 4 The coefficient of x 2 is positive, so the graph will be a positive U-shaped curve.
