Study Notes
### Trigonometry
- For angles between 90⁰ and 180⁰, the cosine is negative.
- The inverse natural function of the cosecant is the sine.
### Algebra
- A function f(t) that equals f(-t) has even symmetry.
- 0.1414 has four significant figures.
- The base of the Naperian logarithm is closest to 2.72.
- If the second derivative of a curve equation is equal to the negative of the same equation, the curve is a sinusoid.
- To obtain a triangle's angle with only side lengths, the law of cosines is used.
