Calculating stationary points also lends itself to the solving of problems that require some variable to be maximised or minimised. Distance education—Manitoba. The diagram shows the plan for a verandah which is to be built on the corner of a cottage. Statisticianswill use calculus to evaluate survey data to help develop business plans.
