Suppose that y = f(x) is a particular solution to the differential equation condition f(2) = 3. A. Find the equation of the tangent line to the graph of y = f(x) at x = 2. y = B. Use your tangent line approximation to approximate f(2.2). f(2.2)≈ dy = 2x + y² with the initial dx

Plant Growth Researchers have found that the probability P that a plant will grow to radius R can be described by the differential equation dPdR=4DRP2 where D is the density of the plants in an area. Source: Ecology. Given the initial condition P(0)=1, find a formula for P in term of R.
