Stationary points - dy/dx =0dy/dx = x² -8x +12 ( differentiating- early a level skill). Solving x² -8x +12=0 gives x=6, x=2 (solving quadratics- gcse skill). Subbing these values bac...

This is a complex question, the proof of which is unlikely to be asked at maths A-level, however the process behind the proof practices fundamental knowledge for the subject. If a student can successfully...

Well that depends on the curve, but if it is a quadratic, we can do it with the following method. We know that differentiating the equation of the curve will give us the equation of the tangent to that cu...

dy/dx means you have to differentiate the equation provided: y = 4x^1/2When we differentiate with respect to x we must multiply the power by the coefficient: 1/2 = power by 4 = coefficient which...

First, make sure that the tutee understands using radians, and get them to do some examples of swapping between radians and degrees to ensure familiarity.Then explain to the tutee that they already intuit...
