What is the formula for calculating the minimum number of teeth on the wheel ?

What is the formula for calculating the minimum number of teeth on the wheel ? Correct Answer T = 2aw/((1+(1/G)((1/G)+2)sin2φ)0.5 – 1)

T ≥ 2aw/((1+(1/G)((1/G)+2)sin2φ)0.5 – 1) This implies that the minimum teeth must always be greater than the value obtained using this formula. In the limit, T = (2aw/(1+(1/G)((1/G)+2)sin2φ)0.5 – 1). The minimum number of teeth on the pinion is given by t = T/G.
