Hi can someone help me with these 2 questions? Thank you

2. Consider the equation in my = y? 1. (i) Show that (3,3,0 = (1,1) is a solution to this equation. .. . dy (11) Find a {iii} Find :13 . 3' (z.yJ=(1'1) (iv) Find all point(s) satisfying the equation at which there is a vertical tangent line. (m.y)=(1.1) 3. Consider the function n) = 31 on [0, 2], and a point a E [0, 2]. Consider the triangle formed by the tangent line to f at a, and the Lines 3: = {l and y = 0. Find the point a such that the triangle has largest possible area, and justify that the area has been maximized
