GGavran reacted to PeroK's post in the thread I Am I misapplying something here? (Exponentials; Euler's identity) with
Informative.
In general, ##f^{-1}(f(z))## is not necessarily equal to ##z##. Can you see why? -
GGavran replied to the thread Vertical Circular motion- A confusing question.The tension force becomes zero when the centripetal force becomes equal to the perpendicular component of the gravitational force.
-
GYou don't need any formula to answer this. You need to understand what kind of circuit element the inductor behaves as in each of the...

Like.
1) proofing ##\lim_{x \to 2^{-} f(x)=10}## $$|x^3 +2-10|<\epsilon$$ $$-\epsilon<x^3-8<\epsilon$$ $$8-\epsilon<x^3<8+\epsilon$$... -

GGavran reacted to songoku's post in the thread Limit of piecewise function using epsilon delta with Like.
Is calculating the bounds based on one - sided limit like post #24? But in post#15, the delta you take is ##|\sqrt[3]{8+\epsilon}-2|##...

GGavran replied to the thread Vertical Circular motion- A confusing question.A circular motion of the bob ends when a tension force in the string becomes zero. At that moment another kind of motion of the bob...

GGavran reacted to microdosemishief's post in the thread Change in Displacement Formulation with Like.
Assuming initial displacement is zero, if x = v₁(t) + ½a(t)², why isnt Δx = x2-x1 = (v₁(t2) + ½a(t2)²) - (v₁(t1) + ½a(t1)²) = v₁(t₂ -...

GGavran reacted to SammyS's post in the thread I Geometry problem of interest with a 3-4-5 triangle with Informative.
Not only is this true for all right triangles, it's true for all triangles in general.

GGavran reacted to Charles Link's post in the thread I Geometry problem of interest with a 3-4-5 triangle with Like.
Very good. ## x^2+(x+d)^2=(x+2d)^2 ## has two solutions when you solve for ## x ## in terms of ## d ##: ##x=3d ## and ## x=-d ##, with...

GGavran replied to the thread I Geometry problem of interest with a 3-4-5 triangle.Just to add that a triangle with sides in the ratio 3:4:5 is the unique right triangle whose sides are in arithmetic progression.

GGavran replied to the thread Change in Displacement Formulation.Both expressions for Δx and are only valid for the case where t1=0.

GGavran replied to the thread Current through an inductor as a function of time.Now, the resistances ## R ##, ## 2R ##, ## 3R ## ,## 4R ## and the voltage source ## V ## can be replaced at terminals B-D by a...
