So I've been working on Pythagorean stuff and it's pretty straight forward but then I got confused over something quite simple.
It's a geometry question so I'll try my best to illustrate the question.
So there's a triangle and we must evaluate whether it's a right angle. The lengths are not...
I'm sorry, I don't think I was clear. I understand that much but I want to know what was wrong with my method, did I do an operation wrong or can you not do it that way, and if so why not? Because it looks like an equation to me and that's how one would usually simplify an equation.
I don't...
Ok so I don't know what is wrong with me, but when it comes to graphs I often get x and y mixed up and the whole thing becomes very confusing.
I had this question
plot a graph using y = 2/3x
The answer is:
if x = 3
y = (2/3 * 3) = 2
x = 3, y = 2
and these are integers which can be plotted...
I'm sorry it appears the source of my confusion was very much that I assumed I was evaluating something when in fact I was originally doing these operations to make it easier to compare which of two expressions were greater. That wasn't clear to me at the time so I was confused why it wasn't...
I'm having trouble understanding how this method works and why it appears not to work on similar questions.
For the question evaluate 3 * sqr(2)
I understand I can square both factors to eliminate the square root.
(3 * 3) * 2 = 18
However this does not appear to work with 2 * sqr(16)
(2 * 2...
