I have no idea how to do this problem can you guys shed some light?
Sqrt[7]^2 == r^2 + r^2 - 2 * r * r * Cos[2 * Pi / 3]
Thanks.

Thanks.
Nope!Gokul43201 said:Is this the problem :
[tex]\sqrt{7}^2 = r^2 + r^2 - 2r^2 cos \left( \frac{2 \pi}{3} \right) [/tex] ?
Can you not simplify the LHS, collect terms in the RHS and plug in the value of the cosine to end up with a trivial quadratic ? Or did I misunderstand the question ?
The best approach to solving a hard math problem is to break it down into smaller, more manageable steps. Start by understanding the problem and identifying any given information. Then, use the appropriate formulas and concepts to solve each step until you reach the final solution.
Practice, practice, practice! The more you work on solving math problems, the better you will become at identifying patterns and applying different strategies. It can also be helpful to work with a study group or seek out additional resources such as textbooks or online tutorials.
If you get stuck on a hard math problem, take a step back and try approaching it from a different angle. You can also try using a different formula or concept to see if it leads to a solution. If you're still stuck, don't be afraid to ask for help from a teacher or classmate.
To check your answer to a hard math problem, you can plug it back into the original equation or problem and see if it works. You can also use online calculators or ask a teacher to review your work and provide feedback. It's important to double-check your answer to avoid any careless mistakes.
If you consistently struggle with solving hard math problems, it may be helpful to review the fundamentals and ensure you have a strong understanding of basic concepts. You can also seek out extra help from a tutor or attend extra practice sessions. Don't be discouraged - with persistence and determination, you can improve your problem-solving skills in math.
