Error

Bits error versus B

Bits error versus x

Derivation

  1. Initial program 0.2

    \[\left(-x \cdot \frac{1}{\tan B}\right) + \frac{1}{\sin B}\]

  2. Applied simplify 0.1

    \[\leadsto \color{blue}{\frac{1}{\sin B} + \frac{-x}{\tan B}}\]
  3. Using strategy rm

  4. Applied clear-num 0.2

    \[\leadsto \frac{1}{\sin B} + \color{blue}{\frac{1}{\frac{\tan B}{-x}}}\]
  5. Removed slow pow expressions
