	Arc length and Chord length		2010-03-13
		From Darryl: Is there a formula to determine the chord length of an arc knowing only the arc length and the arc depth (sagitta)? I know you can't find the radius with only these two inputs, but can you find the chord length? Answered by Harley Weston.
	Cooling		2010-03-07
		From Lori: If a house is always at 20 degrees celsius. Water (tea) boils at 100 degrees celsius. 5 minutes later the tea was 70 degrees celsius. Use an equation to predict the temperature after 20 minutes. Answered by Tyler Wood.
	541.39(1 + i)^15 = 784.09		2009-10-14
		From Fitore: Hi, I noticed that this question was already posted up, however I was hoping I could solve it without having to use logs. Can you please help me? The equation is: 541.39(1 + i)^15 = 784.09 Answered by Penny Nom.
	Find the central angle		2009-08-18
		From Larissa: In a circle, the length of a chord AB is 4 cm and the length of the arc AB is 5 cm. Find the central angle theta, in radians, correct to four decimal places. Then give the answer to the nearest degree. I think I'm supposed to use Newton's method, but am not sure how to start with this problem. Answered by Harley Weston.
	What is so important about quadratics?		2008-11-29
		From zoe: what is so important about quadratics? Answered by Harley Weston.
	Estimate the cube root of 270		2008-03-11
		From Tom: (a) By plotting suitable graphs, estimate to one decimal place the cube root of 270. (b) With reference to your answer to part (a), use 8 iterations of a Bisection Search to refine your estimate. Use the nearest whole numbers either side of your estimate from part (a) as starting values. (c) Using either of your starting values from part (b) as first guess, use the Newton-Raphson method to find the true value of the root (to 6 decimal places). Repeat using the other starting value from part (b) and compare the two results. Answered by Harley Weston.

		From Ned: Given an arc with length of 192 inches (don't know chord length), and arc height of 6 inches, how would one find the radius? Answered by Stephen La Rocque and Harley Weston.
	Solve sin(x)=x^2-x		2007-12-11
		From ming: is there anyway you can solve sin(x)=x^2-x without a calculator? Answered by Stephen La Rocque.

		From victoria: i need help making a poster on emilie du chatelet a great mathematician can you describe the newton principia because i know that she worked on it thanks, victoria Answered by Stephen La Rocque and Penny Nom.
	x^x = 2x		2007-02-22
		From ramsay: This has been bugging me for ages. How do find both real solutions to x^x = 2x? Obviously I have x=2, and there's another at about 0.35, but I can't work it out properly. Any help? Answered by Penny Nom.
	Newton meters and ft-lbs		2006-11-04
		From Michael: What is the correlation between Newton meters and ft-lbs of torque? If an engine has 100ft-lbs of torque,what would that equate to in Newton meters? Answered by Stephen La Rocque.

	Square roots and inequalities		2004-10-25
		From Waheed: Q1. What is the simplest way of finding a square root of any number using just a pen and paper? (I am asking this question because I browsed a few sites a didn't find any method that is simpler than the one I use. so I am just curious.) Q2.

		From William: According to page 126 of Murtha & Willard's "Statistics and Calculus" (Prentice-Hall, 1973), Newton's binomial theorem can proved inductively. I suppose that was his method, which I would like to see. Answered by Penny Nom.
