For any non-zero complex number z, let arg(z) denote the principal argument..[Jee Advanced Question]

This video provides a detailed solution of the following question: For a non-zero complex number z, let arg(z) denote the principal argument of z, with -π is less than arg(z) which is less than or equal to π. Let ω be the cube root of unity for which 0 is less than arg(ω) which is less than π. Let α = arg( Σ [from n=1 to 2025] (-ω)ⁿ ) Find the value of (3α / π). #mathematics #maths #jeeadvanced #complexnumbers #concept
