math question about triangles ooooo ahhhhh
So, let's say there is a right triangle, it has the sides of 1 and 1. Therefore it's hypotenuse is sqrt(2) or 1.414 correct? Now if entering the trigonometric ratio of sine, you would take the opposite side which would be 1 and place it over the hypotenuse

:p
but basically, you try to avoid squaring negatives, since you need to use that little i there to correct it but if you want the square root of 2.557 negative, then the question would be -|2.557| i think

all good, but yeah both of those are the same, except one is rational, the other irrational, and for all intents put the square root on the top, i was informed this today

Do order of operations for this, parenthesis first of course
((first) + second) / third

I have very little knowledge when it comes to physics, but don't you need a location to determine his mass elsewhere? As in, a particular planet, a gravity simulation chamber, so on?

I thought you can't leave a square root in the denominator?

Thankyou kindly! I'll be sure to post more interesting trig questions as they emerge, but so far, when doing my math i come up short by 4 when the answer was in the 1000's, i think it's the rounding of the calculator on here, since i lack one that can do sec, csc, cot and their arc functions.

Oh, it's that one rule thingy where you can't have squareroot on the bottom of a fraction. aighty, wasn't sure, but i vaguely recall that being mentioned years ago, it is of course not present in the book so far as i see.

I actually ran into this same thing later on in the book, it was giving the 6 ratios for a right triangle with 45 corners, the sides are 1, 1, and sqrt(2) once more they state sin is sqrt(2)/2 and cos is sqrt(2)/2 This shouldn't be the case, yet it printed it like that again, in a completely different chapter. I'm trying to reason why they did this the way they did, for instance if they are wrong, how did they reach that conclusion?

It rolls down stairs alone or in pairs, rolls over your neighbor's dog. It's great for a snack and fits on your back. It's Log, Log, Log!
Or log is the basic question "How many of one number do we multiply to get another number?"

To add the scientific notations together, you would get them into the same power, so in this case, change 2*10^3 to 20*10^2 then add it to 1.9*10^2. To add them, you keep the power the same, just modify the numbers themselves, so it would become 21.9*10^2
Same goes for subtraction, just the opposite of adding them.
