Determine a general formula (or formulas) for the solutions to the following equation.?

Then, determine the specific solutions (if any) on the interval [0,2pi).

cos theta= square root 3 divided by 2

How to do this , and can some one explain

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books
