how do i find domain and range of functions on a graph which does not have any numbers or anything marked on it?
it's kinda hard to explain without a picture (i'll see if i can upload one) but does anyone know a general way to figure it out?

I can't understand why in my math book 385/165 = 5x7x11/3x5x11
And it doesn't even explain WHY 385/165 was reduced to 5x7x11/3x5x11
Can anyone explain in detail why??

It's been commonly told that the opposite of 0 is infinity, but what if there was a point that in a number line that was the imaginary junction between infinity and negative infinity on the number line. This would create a number circle of infinite length and turn a classic X,Y 2-D graph into a stretched out sphere.

Anyone ever think of this. Is there any interesting application of this concept?

The function y = A sin((square root of (k/m) * t ) represents the oscilattion of a mass m at the end of a spring. The constant k measures the stiffness of the spring.
a. Find a time at which the mass is farthest from it's equilibrium
position. Find a time at which the mass is moving fastest. Find
a time at which the mass is accelerating fastest.
b. What os the period, T, of the oscillation?
c. Find dT/dm. What does the sign of dT/dm tell you?
