Why does t² integrate to t³/3? Why a third? t² is the area of a square, so integrating it adds up square slices, t by t and dt thick. They stack into a pyramid, and three identical pyramids fill a t × t × t cube, so each one is a third: t³/3. #maths #calculus #alevelmaths #integration #mathstok

Sine or cosine? On a slope, it's the bit almost everyone has to stop and think about. 📐 Turn the slope until it's flat, and the weight is just a tilted force on normal axes. The angle touches the vertical axis, so the part into the slope is mg cos θ and the part down it is mg sin θ. Sine for slope, C for contact. #maths #mechanics #physics #forces #alevelmaths
