• What topic name does this equation go into in physics?
  `A_(y) = A sin\theta`

`\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}`

`\huge \boxed{\sf \: A_(y) = A sin\theta}`

• So, I think this equation will go under Types of Physical quantities, Vector Quantities, Magnitude, Direction, etc. under physics & Trigonometry under Mathematics.
• This formula is used when we need to find the 'y' component of the vector. You need to know basic trigonometry to solve these type of equations & also how to convert between magnitude & angles.
