Homework Statement For the conservationofenergy,calculate the starting height of the bob. This is done with some trigonometry and is ∆h=L−Lcosθ Calculate the initial potential energy of the pendulum for each of your starting angles.Now, using the diameter of the hanging mass (2 cm),and the time...

Thank you. I love you so much!

What equation? And can you please clarify what each variable mean?

Wait. I could just use 1000/n to be able to get the error of 0.01?

Thank you.

So 2500 is the Actual answer right?

You are killing my brain! My question is simple. how do u calculate the actual answer? Look at this website...

I still don't get it. Can you just please tell me how to find the ACTUAL answer for the f(x) x^3 from 0 10? i will just find the error myself.

What does "e" mean? just please tell me instructions on how to get the answer. please

What?I still don't understand!we haven't learned those equations yet.

Moderator's note: This thread is a perfect example of what not to do in the homework help forums. It is unacceptable for the opening poster not to work through the problem and to demand answers. It is inappropriate for the helper to give out those answers, or tell the poster exactly what to do...
