Consider the function f(x) = x cos x. Out of all the many tangent lines of f(x), determine the one that is parallel to the line y = Tt (x + 1). Answer the following questions: a. What is the slope of the tangent line in question? b. What is the numerical value of y' = f'(x) associated to the tangent line? c. At what coordinates does the tangent line intersect f (x)? d. What is the equation of the said tangent line?
