Study Notes
Proving Properties of Abstract Objects
- The primary method used in mathematics to prove properties of abstract objects is through deductive reasoning from axioms.
Benefits of Mathematics
- Mathematics is applied in various areas, including natural sciences, engineering, economics, and social sciences, among others.
Subdisciplines of Modern Mathematics
- The major subdisciplines of modern mathematics include pure mathematics and applied mathematics.
Fundamental Truths of Mathematics
- The fundamental truths of mathematics are independent from human thought and opinion.
Applied Mathematics
- Applied mathematics includes areas such as physics, engineering, and computer science.
Trigonometric Ratios
- The sine of an acute angle in a right triangle is defined as the ratio of the opposite side to the hypotenuse.
Sine and Cosine Notation
- The sine and cosine functions for an angle θ are denoted as sin(θ) and cos(θ).
Modeling with Sine and Cosine
- The sine and cosine functions are commonly used to model periodic phenomena, such as sound waves, light waves, and electrical signals.
