Find the equation of the tangent to: a y = p2x + 1 at x = 4 b y = 1 2 x at x = 1 c f(x) = x 1 3x at (1, 1 4 ) d f(x) = x2 1 x at (2, 4).
▯ Precisionism: painting and photography movements Painting: inspired by French Paul Saison (did a lot with shapes) and cubism (new ideas of angles and planes) o Not a formal group, no manifesto, but a group of like-minded people o Called cubist realists Photography: Charles Sheeler (he did painting and photography and sometimes copied his photographs into paintings) o Interested in forms and shapes and largely contact printing, printed it directly on paper to get a precise, clear, sharp detail in (diff. techniques + traits from painting but the idea is the same) o Cubism influence (emphasis on geometry and plane) but the
