Systems such as the Red Green Blue system or the Tint Brightness Shade system classify the color spectrum using mathematical values. But the arts are not the only subjects that use mathematics. These relationships often take the form of quadratic and other polynomial equations, trigonometric equations, exponential and logarithmic equations, and other common mathematical relations. To model values, one must have a fairly good knowledge of mathematical relations. Model equations predict values of the experiment in untested situations.
Many occupations require the use of mathematics.
All the scientific uses above apply in the scientific fields of the real world. Speaking of proportion, architects use mathematics in many ways. Conic sections are quite popular with architects, along with other geometric figures. Not only do they have to make everything pleasing to the eye, they must calculate the weight distribution and make sure that the structure will not fall. The construction workers must be able to understand the measurements and specifications for their work.
