1a. Find the equation of a tangent line to the curve f(x) = ln(2−x)/x + 3x at the point (1, 3).
1b. Suppose the following function is defined implicitly by the equation, Find dy/dx x^2 − 3y^2 + 6e^x = 4x^2y + 5
2. Using only the definition of derivative as a limit, calculate f(x) where f(x) = 1/x − 5
