    Is Δθ in a circle equal to the angle in a velocity vectors triangle?

    Delta2 and Clara I appreciate your explanation but can you please describe some '90 degree usage'.

    Is Δθ in a circle equal to the angle in a velocity vectors triangle?

    How is Δθ in circle equals to angle in velocity vectors triangle? I tried using simple geometry but I can't.

    Stuck Again: Find the Correct Answer to ƒ(x)

    Yes it must be like ƒ(x) = (x2 - x - 42) / (x-7).

    Stuck Again: Find the Correct Answer to ƒ(x)

    I was doin' some coursera quiz. It asked this question : Let ƒ(x) = (x2 - x - 42) / x-7 find as x → 7. Now I approach x from both sides and it get me 2 different answer. So which one is correct: 13 or 14?

    How to calculate instantaneous acceleration if -->

    First I used the formula dv/dt but I am used to have a ƒ(x) in the questions I usually did.
