All there is on the bladder itself are; a measurement line on the side to tell me how much water is in the bladder, and various pictures under the forward slash symbol to tell me what I can't put in it. Do you know anything about TPU and/or EVA?
I was just given a hydration bladder:
https://www.amazon.com/dp/B00JY9WFO2/?tag=pfamazon01-20
But NOWHERE on the package does it say it is BPA free. Almost every product now says it is BPA (Including glass jars which I find to be redundant.) free. Another website says it is made out of TPU and...
how was the trigonometric functions created? how did mathematicians find cosine, sine, tangent, etc. without a calculator. basically how would i find the trigonometric functions after the collapse of civilization and it was up to me to rewrite all the charts and program all the calculators that...
Is there scientific evidence that sleeping next to a wireless modem is harmful? What is the minimum safe distance? Would you sleep next to a wireless modem? I am very worried that sleeping next to a modem can be harmful. I live in a very small appartment, and don't have many choices. Please help.
I do not care what the average iq is. I want to know what the most common IQ is. I mean...For example:
120
120
120
120
120
120
40
40
Average of all this is 100. But 100 is not the mean IQ. I don't know if the bell curve is just assuming that the most common IQ is between 90-110 simply because...
Hello I was trying to solve this sample problem, but I really don't get it.
The book says this word by word:
The equation sin3x=1 implies
3x=(pi/2)+2kpi, k an integer.
x= (pi/6)+(2kpi/3), k an integer *Divide each side by 3.
Because x is not restricted to a finite interval, the given...
I was experimenting with frying eggs in vegitable oil. The result tasted good but it made my mouth oily all day. I'm I going to be all right? How long is it till the oil is out of my body if ever. (I know oil is hydrophilic) Is my body going to be able to get rid of it?! Is the inside of my body...
Okay this has been bothering me, I know what the x-axis on sine graph mean, but not the y axis. I know when I type for example: sin(pi) I will get 1. But what is that 1? I know its the y cordnate. But what is it?
I know what the Trigonometric functions are but I don't know what they mean.
For example sinθ=opp/hyp, but It just seems like I am plugging in the sides to get random numbers. I JUST started learning Trigonometry, I am not that advanced in math, so can you please explain it in such a way...
I went through the SAME THING I took physics in high school and I fell in love with it. Problem was I couldn't even solve for X to save my life. I couldn't add or subtract fractions, I couldn't do long division, I had a hard time adding/subtracting single digit numbers in my head. (I was in...
I got a 30kg rock in space, no gravity, no friction. It is traveling at a CONSTANT speed of 100m/s. According Newton's second law, There should be NO force because there is NO acceleration. But I know if it hits another object it will either move the object or put a hole in it so I know there is...
