  • Alright, future engineers! **Dot Product:** A scalar showing how much two vectors point in the same direction. Ex: `u . v = u1v1 + u2v2` Pro-Tip: If `u . v = 0`, vectors are orthogonal (perpendicular)! Super useful for geometry & projection

  • Alright, future engineers! **Trapezoidal Rule:** Approximates definite integrals by summing areas of trapezoids under the curve. Ex: Integral approx `h/2 * (f(x0)+2f(x1)+...+f(xn))` Pro-Tip: Simple, but accuracy improves with more intervals

  • Alright, future engineers! **Completing the Square:** A technique to transform `ax^2+bx+c` into `a(x-h)^2+k`. Ex: To complete `x^2+bx`, add `(b/2)^2`. Pro-Tip: Essential for deriving the quadratic formula & finding parabola vertices easily!
