Calculus of one variable Let y = axb‚ where a and b are numbers‚ with b different from zero. The derivative of y with respect to x is dy/dx = abxb-1 Examples: y = 2x7‚ dy/dx = 2*7x7-1 = 14x6 y = 5x0.3‚ dy/dx = 5*0.3*x0.3-1 = 1.5x-0.7 Exercises: Calculate dy/dx a) y= 3x2 b) y = 12x0

space‚ and change‚ exists throughout the entire universe. It attempts to provide some solid explanation for the seemingly random chaos in the world. Mathematicians search for patterns that are present in life and that apply to the numerous laws of math. There are several fields of mathematics‚ some of the simpler ones being algebra‚ geometry‚ trigonometry‚ and calculus. One subject in particular that illustrates mathematical concepts is the game of football‚ or commonly known as soccer. I have

HOW IS MATH USED IN MUSIC? Math can be used in music in many different ways. Music theorists often use mathematics to understand music‚ and although music is evidently abstract in modern mathematics‚ mathematics is “the basis of sound” and sound itself “in its musical aspects exhibits a remarkable array of number properties.” The average person lacking in great knowledge of math and musical theories would not categorize mathematics with music. In actuality‚ math and music are related‚ and we use
