The first question is to find k in terms of alpha, 1 is my first attempt and 2 is my second. I tried to write both answers I got from those 2 but it said incorrect. Also I have to cram a lot of maths topics in a short time and I'm finding that the solutions are sometimes methods I knew about but just didn't think to use there because I'm so used to the typical method solutions for each topic,, is there like any way I can get better at remembering techniques other than just doing random practice questions which happen to be trickier. I wish I could just get really good at algebra and come up with the stuff myself but that doesn't seem like something achievable in 3 days
