Alright, future engineers! **Cartesian Product:** The set of all ordered pairs (a,b) where 'a' is from set A & 'b' from set B. Ex: A={1,2}, B={x,y} => AxB = {(1,x), (1,y), (2,x), (2,y)}. Pro-Tip: `|AxB| = |A| * |B|`. Use for counting total
Alright, future engineers! **Vertex Degree:** The number of edges connected to a vertex (node) in a graph. Ex: If 'A' connects to 'B' & 'C', deg(A)=2. Pro-Tip: Sum of all degrees = 2 * (total edges). Great for checking graph validity! #Grap
Alright, future engineers! **Trapezoidal Rule:** Approximates definite integrals by summing areas of trapezoids under the curve. Ex: `Area ≈ h/2 * (f0 + fn + 2*sum(f_mid))` Pro-Tip: Halving the step size (h) generally halves the error. Get
