• What topic name does this equation go into in physics?$A_{x} = A cos\theta$

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

$\huge \boxed{\sf \: A_{x} = A cos\theta}$

• 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 'x' component of the vector. You need to know basic trigonometry to solve these type of equations & also how to convert between magnitude & angles.
