Let y = f(x) be a particular solution of the differential equation dy/dx = 1 / xy with f(1) = 2. (a) Find d2y dx2 at the point (1, 2).
(b) Write an equation for the line tangent to the graph of f at (1, 2) and use it to approximate f(1.1). Is the approximation for f(1.1) greater than or less than f(1.1)? Explain your reasoning.
(c) Find the solution of the given differential equation that satisfies the initial condition f(1) = 2.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
