Hello Math Connoisseurs,

I am starting my Master studies in Cinematography and have to, for the first time in my life since 10th grade, study math to prepare for my extremely competitive studies. I have always been very self conscious of my math knowledge and am trying my best to prepare. 

I've been sent a list of questions from the University and I was hoping people here can help me prepare. It's only 7 questions varying from equations to trigonometry. Would anybody be willing to help me study for this?

Thank you.
