𝑀O(1; −1; 2) nuqtadagi 𝑧 = 𝑥2 + 𝑦2 aylanma paraboloidiga urinuvchi tekislik tenglamasini yozing. Написать уравнения касательной плоскости к параболоиду
вращения 𝑧 = 𝑥2 + 𝑦2 в точке 𝑀O(1; −1; 2). Write the equations of the tangent plane to paraboloid 𝑧 = 𝑥2 + 𝑦2 at point 𝑀O(1; −1; 2).
𝑧 − 2 = 2 · (𝑥 − 1) − 2 · (𝑦 + 1)
𝑧 − 2 = 2 · (𝑥 + 1) − 2 · (𝑦 + 1)
𝑧 − 2 = 2 · (𝑥 − 1) − 2 · (𝑦 − 1)
𝑧 − 2 = 2 · (𝑥 − 1) + 2 · (𝑦 + 1)
