here's the better proof
Let's start with the finding of x = 10n+L by writing x in a form that can be expanded to calculate easier.
Let n be all digits except last (ex:x=1234,n=123)
Let L be last digit(ex:x=1234,L=4)
x=Cn+L
where C stands for constant
(x-L)=Cn
therefore
any (number x)-(last...
sorry for the bad proof I made it up on the spot since I found this formula by experimenting with numbers but that's no excuse so I'll send you a better one later today and yes it is useless compared to Grade 3 algebra way of doing this 452=2025 or today with a calculator or in your head which I...
sorry for this horrid proof and I will send you a better one and this formula maybe useless compared to a calculator or the good old grade 3 math way but it's another way of getting to it you see.
Hey thanks and this is my first time posting so that's why I didn't know what section to put my formula question in and by the way this is only for x direction the other one for cos I proved mathematically on paper but didn't type up yet.
The proof of the
Exponential Equation
For starts this proof and example will give you tools and tricks to find any number squared or cubed etc like 57^2=A and even 1234^3
So x^2=A
Where A is the Answer
and x is the #
now think of n being every digit except L where L is last digit
Ex: 57...
Direction of a plane proof
48. A pilot wants to land at a small lake that is [N30.0 ̊W] of the airport that she is starting from. The wind has a velocity of 25.0 m/s[W] and the air speed of the plane is 1.90 × 10^2 m/s . What direction will the plane have to fly to get to its destination? What...
