When an angle is small and in radians we can use approximations for sin(x), cos(x) and tan(x) to find limits for other trigonometric functions as these tutorials show.
The angular sizes of.
When we were able to derive until the part where $n \lambda =a \sin(\theta)$, we need to apply small angle approximation and get to $n \lambda =a \tan(\theta)$.
