r=3, h=5, pi=3.14159.\n\nJust plug these into the formula and you're set.

Well, I can see that one possible solution is r = 0, and my calculator says the other answer is r = 0.0809394063, so hopefully that helps...

i = cos(pi/2) + isin(pi/2)\n\nsqrt(i) = cos(pi/4) + i sin(pi/4) = sqrt(2)/2 + i sqrt(2)/2\n\nif z = r(cos(t) + i sin(t), to take the square root, you take the square root of r (in your case 1) and divide t by 2.

I have seen this question sometime this weekend!\nYour question is more complete, though.\nV=pi.r^2h=1000\nS=2pi.r(r+h)\n\nExpress h in terms of r\nh=V/(pi.r^2)\n\nSubstitute in S\nS=2pi.r(r+V/(pi.r^2))\n\nDifferentiate S w.r.t. r,\ndS/dr=2*pi*(V/(pi.r^2+r-2V/(pi.r^2))\n\nEquating this to zero and solve for r:\nr=(V/(2pi))^(1/3) and a negative root\nFor V=1000,\nr=5.41926\nh=1000/(pi.r^2)=10.8385\n\nThe result is not surprising, as the dimensions resemble that of a cube, or a sphere, which have the minimum surface area for a given volume.

by the simplified version of the Henderson hasselbach equation\n\npH=pka + log(A-/HA)\n\npH=-log(Ka) + log (1) = -log(Ka) + 0 = -log(1.8x10^-4)= 3.77\n\n- 2 sigfigs! Since when you take the log you should have as many decimal places as numbers you started with.\n\n-By consequence, this is at the point known as the Equivalence point.

You'd have to use the chain rule for the square root, then the quotient rule for what's inside.\n\nf ' (x) = (1/2) [(2x³ - 7) / (4x + 1)]^(-1/2) times the derivative of the radicand.\nFor that, the quotient rule gives:\n[6x²(4x + 1) - 4(2x³ - 7)] / (4x + 1)²\n\nThere's most likely some simplifying to be done, but that should get you on the right path.\n\nGood luck!

use the distance formula\nsqrt(3^2+(-sqr3)^2)=?

Just plug in 1 for x.\n√(1-1) = √0 = 0

proof :\n\n1 -1 = 1 - 1\nlhs: 1 - 1 \nrhs: 1 -1 \n\nthaking 1 common  from lhs v hav \n1 (1 - 1 )\n\nexpanding rhs by the formula a^2 - b^2 = (a+b)(a-b)\n\n(1-1)(1+1)\n\nthus we hav \n\n1 (1 - 1 ) = ( 1 - 1 ) (1 + 1 )\ndividing througout by ( 1 - 1 )\n\nwe get 1 = 1 + 1\n\n\n\nDoes this help u??
