i haven't :(

OK could you give me an integral calculus tutorial? :smile:

the idea is that if a circle was turned around 180 degrees on a line through the middle of it, and if every frame of its rotation was kept there, it would make a sphere. The circumference is the distance the edge of the circle has to travel 360 degrees. hmm... maybe the problem is that different...

My brother thought of an alternative formula for the volume of a sphere: (1/2)(∏R2)(2∏R). it didn't work could anyone tell me why?

phew :rolleyes:! thanks.:biggrin:

any number you like. but you have to use a least 3-5 different numbers. (isn't it hard? :P )

How do I solve this? :eek: [attached the image of question :)]

umm... it makes CO2 or some other gas? :rolleyes:.. and fizzes?

Potassium bitartrate, also known as potassium hydrogen tartrate, has formula KC4H5O6, is a byproduct of winemaking. In cooking it is known as cream of tartar. It is the potassium acid salt of tartaric acid, a carboxylic acid. Also is, according to NIST, used as a primary reference standard for a...

Cream of tartar is KHC4H4O6

what happens when you mix cream of tartar, baking soda, and water together? (i've never had time to try this):confused: KHC4H4O6 + NaHCO3 + H2O = ?
