Expansion Theorem for Determinants
- cofactor
- (i) The expression $a_{i1} A_{i1} + a_{i2} + \cdots + a_{in} A_{in}$ has the same value for any $i$, and is the definition of $\det \mathbf A$, the determinant of $\mathbf A$.
Cosine of Sum
- compound angle formulae (in trigonometry)
- $\map \cos {a \pm b} = \cos a \cos b \pm \sin a \sin b$
Equiangular Spiral
- equiangular spiral
- The equation can be written $r = k \theta + b$
Transversable Graph

Primitive of $\dfrac 1 {\sqrt {a^2 + x^2} }$
- Appendix $7$: Integrals
- $\ds \int \frac {\d x} {\sqrt {a^2 + x^2} } = \dfrac 1 a \tan^{-1} {\frac x a}$
Primitive of $\sqrt {a^2 - x^2}$
- Appendix $7$: Integrals
- $\ds \int \sqrt {x^2 + x^2} \rd x = \frac 1 2 x \sqrt {x^2 + x^2} + \frac 1 2 a^2 \sin^{-1} \frac x a$
