The lowercase symbol represents many things, such as an unknown variable in trigonometry, or a plane angle in geometry. The uppercase symbol can be used for a dimension of temperature or represents the time decay of options in finance.
WebThe Minus Case. Similarly, for the minus case, we equate a sin θ − b cos θ with the expansion of R sin (θ − α) as follows (note the minus signs carefully): . a sin θ − b cos θ ≡ R cos α sin θ − R sin α cos θ. Once again we will obtain (try it yourself!): `alpha=arctan\ b/a` and `R=sqrt(a^2+b^2)` Our equation for the minus case is: WebMay 9, 2024 · Instantons, renormalons and the theta angle in integrable sigma models.
