Ok this is really annoying me:
The question is

(sigma) where n=1 to infinity; is equal to:

[(-3)^(n-1)]/[8^n]

I understand it is an alternating series and that it is convergent.

But, I do not know how to go about figuring out what it converges to.

I don't know how to go about doing this.

Help please...

I Just read a wrinkle in time and I am kinda confused. I am studying geometery and it is hard enough for me and the book goes against every thing I have learned. If you could could you include diagrams of 5-D things which are also included in the book. Is there a movie based on the book? It might help me understand it better.

An aluminum cup with mass 0.55 kg holds 0.81 kg of water. Both the cup and the water have a temperature of 25.87 °C. If a 0.67-kg piece of copper at 76.9 °C is added to the cup, what is the final equilibrium temperature in °C? You may assume that the cup, water, and copper are well insulated from anything else.
