A graphing calculator may NOT be used for the following problem

Question

The spread of a fungal infection in an ant colony can be modeled by dy/dt = (y+1) / 2√ t where t is the time in hours and y is the percent of the ants infected. At t = 1 only three percent of the ants are infected. a) Write an equation for the line tangent to the graph of y at t = 1. Use the tangent line to approximate the percentage of the colony infected at t = 1.2. b) Find y explicitly in terms of t.
