what exactly does Δy/Δx mean. for instance i know that when y=x2 Δy/Δx=2x but what does Δx/Δy equal? also why is the derivative always Δx/Δy? also what does Δx by itself mean for instance if y=x2 what is Δx i appreciate any and all answers thanks:smile:

Say i drop a 1kg rock into a pond from a height of 2 meters.i want to find out how high the water wave will be. how would i go about this problem?

It worked thanks :).but why do you multiply by x^4 instead of X^3 or something like that?

What are some good documentaries on cell theory cell membranes DNA or genetics.Also documentaries on bacteria and viruses would be good.

I'm sorry i am new to differentiation but how to i do the division?

i fixed it.the coefficients are right but the exponents don't match up.

f(x)=x^2-3x-3x^-2+5x^-3 I need help finding the 1st derivative of this function using the power rule.If you can help can you explain how you got the answer.I tried like five times but the differentiation calculator says I am getting the wrong answer.heres how o attempted it. f(x)'=(2)(x)^2-1 -...

1.Does a gravitational field ever end for instance do we experience a gravitational force from a star light years away. 2.if there are two objects in space one 100kg and another 1kg.According to Newtons law of Universal Gravitation there will be an attractive force between these two objects...

does size matter when it comes to mass.For instance can something the size of a marble weight as much as a planet like earth?

So if this happened on Earth ignoring air resistance would the person on the platform feel weightless?

I am having trouble understanding g-force.So if a object with a mass of 100 kg is sitting on a platform in space.If the platform was accelerating at 10 m/s^2 upwards would the weight of the object be 1000 kg? If so why?
