Given that the minimum positive period of the function y = sin (Wx + quarter π) (W > 0) is 2 / 5 π, then w is equal to A 5 b 5 π C 5 / 4 D 5 / 2

Given that the minimum positive period of the function y = sin (Wx + quarter π) (W > 0) is 2 / 5 π, then w is equal to A 5 b 5 π C 5 / 4 D 5 / 2

T=2π/w=2π/5
w=5
