Brainlet here, how the hell do I calculate two angles needed for equilibrium when I know 3 vector magnitudes and one angle? The numbers are:
Vector Magnitude (g) | Angle
168.6 g 0°
99.7 g ?
119.9 g ?

What is the best(fastest) way to reliably prep for the ACT and SAT considering I've been out of high school for nearly 8 years?

For the writing section, there is a set guideline that they look for. Look up how to pass the writing section and you'll be fine.

For the reading, you have to know a lot of vocab. They don't allow you to take advantage of suffix and prefix usage because they don't want you to be able to study for the exam, they want you to use you built-up vocabulary from many years of experience.

For math, it's mostly your innate logic combined with algebra and trig. At the very least, you can learn algebra and trigonometry before taking the exam.

Two questions concerning dentistry:
1. Is there any legitimacy to conspiracy theories about fluoride in the water?
2. Do fillings and dental fissures have health side effects?

Is ho3 2016 a second moon or a completely separate celestial body?

Why Mathematica keep using Log[e]? Isn't it just 1 ffs
Is there a way to change it?

Does Mathematica default log to base e, or is it like ti83/84 that defaults to base 10

Today I got my first Fluid Mechanics class and I noticed there won't be any conformal maps in the curriculum. Is there an introductory text or a book that focus on this application for conformal maps and maybe the underlying mathematical principles? I like mathematics and I was disappointed when I noticed it won't be covered in class. One with exercises will be much appreciated.

You probably just need to use a simplifying function around the results.

>1. Is there any legitimacy to conspiracy theories about fluoride in the water?
It is a fact that over-dosage of fluoride causes health problems. Wether the low dosage recommended to avoid cavities present long-term problems is a matter of debate. But there was a (anecdotal) case in my state where the water company put too little fluoride in the water. So, how much do you trust your company not to put too much in it?
