Mathematics can help us in our everyday lives. Mathematics proves useful in many fields of study while in school. Furthermore, a student of musical theory must understand the mathematical relationships among the different pitches. Although music is not a vital for understanding the world, the world generally agrees that it is a good thing to understand. Another nonessential course that uses mathematics is art.
Many geometrical relationships come into play in many varieties of art.
Colors also have mathematical relationships with one another. 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.
