The Circle Formula - ANS-(x - a)² + (y - b)² = r² Where (a,b) is the centre and (x,y) is any point on the circle. The Discriminant - ANS-b² - 4ac Where 0 gives a tangent (repeated root); > 0 gives two real roots; < 0 gives no real roots; d²y/dx² > 0 = minimum point SUVAT - ANS-v = u + at s = ut + 0.5at² v² = u² + 2as s = vt - 0.5at² s = 0.5t(u + v) Product Rule - ANS-dy/dx = u(dv/dx) + v(du/dx) Quotient Rule - ANS-dy/dx = (v(du/dx) - u(dv/dx)) / v² Where the ori...
