sin(2x) is always between -1 and 1.
Since sin(pi/2) is the first time that it reaches 1,
sin(2x)=1 when 2x = pi/2
That is, when x = pi/4
If you don't know wtf, just take a look at the graph and see where it reaches its maximum.
What is the smallest value for x where y = sin 2x reaches its maximum ...wtf that means.

What graph ...?
Ok, so the quadratic 4 quadrant graph...?
i appreciate the help but I can't see it ...

Hmmm. I think what we have here is a failure to communicate...
The graph of sin(2x) is here. You can plainly see that it reaches its maximum at x = pi/4.

Not sure what quadratic you are referring to. If you instead meant sin^2(x), then that is a max at x = pi/2, since sin(pi/2) = 1. Now, sin(3pi/2) is -1, so sin^2(x) is also 1 there, but pi/2 comes first.

I just meant a 4 quad graph ...x and y intersecting like you have in the link.
OK, this part is a trig rule?
sin(2x) is always between -1 and 1.
Because it covers 2 integers? One on either side of 0 (origin?)On the x axis?
In this equation, they show no graph.
If that matters. How would i know that the graph runs in units of .5p (x axis) or .5p up and down the y axis?
Looking at the graph, I see where sin(pi/2) = 1.
I can see here that you are dividing each side by 2 and that's how we end up with p/4.
Can you put it in a proper equation form? I know this is tedious and ultra simplistic for you Steve, but for me it's like trying to read Egyptian hieroglyphics.
You can't imagine how much I want to understand this.
Thanks again.

Steve, let's take this up a notch.

i can send you a joinme link then you can see inside my pc while we talk on the phone together ...?
We can do some equations in real time with audio guidance ....?
