English: So u_(x) is this so that is so So maybe you can expect the calculation will be simpler if you choose maybe $- \frac{}{2}$ because you see minus both places so I can take it So you can choose ok I have chosen alpha beta as real and imaginary parts of ξ you can also choose real and imaginary parts of η, there is no issue ok so you can choose so this is what my u_(x).
Telugu: కాబట్టి u_(x) ఇది కాబట్టి $u_{x} = - \left( \frac{1}{2}u_{\alpha} + \frac{}{2}u_{\beta} \right)$ కాబట్టి మీరు బహుశా $- \frac{}{2}$ని ఎంచుకుంటే గణన సరళంగా ఉంటుందని మీరు ఆశించవచ్చు.
