Create and complete a function M-file that will receive an input, ? , and output the corresponding conversion to radians within the range of a complete circle. For each 30? increment, the output should be displayed as a string, (i.e. pi/2 , pi/4 ,etc.), and any other degree to be displayed numerically.
I'm using Matlab, explanations are appreciated.

A greenhouse (30’x20’x10’) in Yuma, Arizona needs to be cooled from an outside temperature of 110oF to an indoor 75oF. The RH outside is 4% and the greenhouse requires 5 air changes per hour. Determine the amount of water required per hour to achieve this level of Evaporative cooling. Please state your answer in pounds of water.

Within a large catering organization many slices of bread must be buttered. This is a tedious and time consuming task. You are required to design an automatic process of applying the butter to the bread.
i. For the Design Specification, list the five most important requirements of this product in rank order.
ii. Generate five concept designs that meet the Design Specification requirements in (i). Produce simple sketches of each of your concepts and label the key features. (Note! Your sketch and labeling alone must communicate your concept ideas).
iii. Using the requirements in (i) and the concepts in (ii), rank each design and briefly comment on the suitability of the selected design.
