GGavran replied to the thread Geometry: Similar Shapes.The equation which describes both options should be written in the next form $$ \frac{8+x}{12+3}=\left(\frac{8}{12}\right)^{\pm1} $$.

GGavran replied to the thread I Problem in understanding instantaneous velocity.The average velocity is the rate of change of position over a time interval, while the instantaneous velocity is the rate of change of...

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...

GSuppose you have ten ping pong balls labeled one through ten. You pull two balls at a time out of a random mixer and record the...
-
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...

GCould you clarify when we should use the notation 'tan⁻¹' versus 'arctan' in mathematics? Also, how do we determine when to work in...

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##...
