MCQs: Zyada tar files se thay. Short & Long Questions: Change of coordinates matrix find karni thi from B to C. IVP problem: V₁, V₂ ki values aur x₀ diya hua tha; xt = Ax solve karna tha. Basis problem: x₁, x₂ ki values given theen, un se v₁, v₂ find karne thay. Set diya hua tha, check karna tha orthogonal hai ya nahi. Matrix A given thi, P matrix find karni thi for A = PDP⁻¹. Casorati matrix se batana tha ke signals independent hain ya nahi. Matrix A ke elements equations ki form mein thay; un se u, v, w vectors separate kar ke likhne thay. Overall paper conceptual aur practice-based tha.
