In the NCEES Handbook there is a formula for real power flow, but it does not refer to reactive power flow. In the study guide I am using, the equation for reactive power flow is shown as the image below. I'm trying to understand how this equation is derived, since I won't have access to it during the exam. ![IMG_1112.jpeg IMG_1112.jpeg](https://cdn.imagearchive.com/engineerboards/data/attachments/20/20584-2d103aa87001289e1a64b6d3773f4418.jpg)
Thank you in advance for any guidance you can provide!
