Science & Mathematics - 8 November 2006

I am trying to find a program or even a spreadsheet that will turn data that I have into an equation that equals an answer that I already have. I basically have the data and the answer but I need to know the equation. Thanks!

How would you use the derivative of cosx to prove that

d/dx (secx) = secxtanx

I know the derivative of cosx = -sinx, but I keep getting stuck with all my attempts at answering

Any help would be much appreciated!

The largest popcorn ball ever made was finished on April 29, 1995 in Sac County, Indiana. It weighed 2,225 pounds and was 6 ft high. How many cubic feet of popcorn made up the popcorn ball?

The tree with the greatest volume of wood in the world is the General Sherman Tree in Sequoia National Park, CA. This tree is 275 feet high, and the base of its trunk has a radius of 16 feet. If the trunk of the tree has a shape between that of a cylinder and a cone, what is the maximum and minimum volume of wood that it contains? Round answers to the nearest cubic foot.)

A heavy ball swings on a string in a circular arc of radius 2 m.

The two highest points are Q and Q' where the string is 29 degrees from the vertical. Point P is the lowest point where the string is vertically down.

acceleration due to gravity is 9.8 m/s^2.

What is the ball's speed at point P? Neglect air resistance and other frictional forces.

A co-worker of mine just returned to work due to being off for gall bladder surgery. All is fine with him and he has the expected incisions and protection on them.

Question comes here... For some reason, he has a patch of leg hair shaved from about the top of his thigh (below his hip) to about the top of his knee (on the side, not the front of the leg). He says it is oval shaped and actually didn't notice it until after a few showers.

He is afraid to call the hospital to ask why (for fear of wasting their time) so I thought I'd inquire to a website like this.

Anyone have any ideas why his thigh would be shaved for gall badder surgery?

I have 8 billiards balls. They all have he same weight, except one of them is heavier than the rest. I have a balance scale that just tips to one side when that side is heavier, but doesn’t give me readings/measurements. What is the least number of times I can weigh the balls in order to find the heaviest ball? Explain
