GGavran replied to the thread Limit of piecewise function using epsilon delta.The post #15 was my mistake. When ## x\to 2^- ## ## \sqrt[3]{8-\epsilon}-2\lt x-2\lt\sqrt[3]{8+\epsilon}-2 ## does not imply ##...

GGavran replied to the thread B (Electric) current is not a vector quantity.You are right. ## dq ## means flow of electric charge in the equation ## i=dq/dt ##. A rate of flow of a scalar quantity is a scalar...

GGavran replied to the thread Limit of piecewise function using epsilon delta.## x-2\lt0 ## and ## \sqrt[3]{8+\epsilon}-2\gt0 ## implies that ## x-2\lt\sqrt[3]{8+\epsilon}-2 ## always holds so ##...

GGavran reacted to bob012345's post in the thread B Geometry Puzzle with 20 points in a cross pattern with
Informative.
If I remember, that was so two weeks ago, probably what I meant by the permutations, was the relative rotations of the squares with... -
GGavran replied to the thread B Geometry Puzzle with 20 points in a cross pattern.I do not understand your statement. There are four squares and every square has four points. Every option must have at least one point...

GGavran replied to the thread Limit of piecewise function using epsilon delta.I have used an online graphing calculator tool and I have found that $$ \delta=|\sqrt[3]{8+\epsilon}-2| $$. I am doubtful about finding...

GFirst, for a problem asking you to solve an equation with several variables, the problem will usually ask you to solve for one of the...

GGavran reacted to Mike_bb's post in the thread I How to find the path if we only know the velocity (without common formulas)? with
Like.
Hello! I invented the problem and I try to solve it: Let we only know velocity of moving particle: ##v(t)## from ##t=a## to ##t=b##... -
GGavran replied to the thread I How to find the path if we only know the velocity (without common formulas)?.If you are not allowed to use the standard approach $$ \vec s=\int_{a_1}^{b_1}\vec v(t)dt $$ try to solve the problem by using the...

GGavran reacted to kuruman's post in the thread Two charged spheres connected to walls by two springs with Informative.
Where did you get this expression for the electrical force? If the spheres are initially separated by ##2a## and you bring them closer...
