Find the points on the curve where the tangent is horizontal or vertical. If you have a graphing device, graph the curve to check your work. (Enter your answers as a comma-separated list of ordered pairs.) x = t³ - 3t, y = t² - 3 horizontal tangent vertical tangent (x, y) = (x, y) =
Find an equation of the tangent to the curve at the point corresponding to the given value of the parameter. x = t³ + 1, y = t¹0 + t; t = -1 y =
