- Simplify the expression: 2sin(x) + 3cos(x) Answer: √5 sin(x + φ)
- Solve the equation: 2x^2 + 5x - 3 = 0 Answer: x = -1 or x = 3/2
- Find the gradient of the tangent to the curve y = x^3 - 2x^2 + x at the point where x = 1. Answer: 2
- Solve the inequality: 2x - 5 > 3 Answer: x > 4
Paper 2: Mechanics
