Pizza Pie Problem: You and your two friends have purchased a pizza of radius "r" and you wish to divide it into three equal pieces by making vertial cuts similar to the ones shown below - obvously one of the cuts  is in the center.....when you find one more, you'll have the problem solved!!! (Note: The illustration indicates a radius of 3 , but the actual radius doesn't matter, since all circles are similar.)  The question is: Where should the cuts be made??

Your answer could be in terms of "r," or in terms of some angle "theta."  You might also consider letting the exact center of the pizza be (0,0).  Hint: The problem CAN  be solved with calculus, but trig will work, too - I've done it both ways - if I remember correctly. Also.......I believe you'll need a "solver" to "finish" your answer out......you will know when you have reached that point!!

Good luck!!

Yes this is a very big problem. I dont mind that the Anonymous dont do it because  a third of the time the Anonymous are screwing around but the members should at the very least give a thumbs up.  

(-2x) 5 + 3x - 4x + (-1) (-x)

=-10x-x+x

=10x

hey you guys and gals.....I DUNNO THE ANSWER I JUST SEEN THAT THIS WAS A LITTLE WEBSITE...SO YAH..BYE NOW

ok you know thats fine too......

No.

no reason to cuss

Hmm!  Unusual to have 180 radians.  What if the 180 is 180°, or $$\pi$$ radians? In this case we get a different set of results:

The values of x are now given by $$x=(n+\frac{1}{2})\pi$$ where n is an integer.

Goddamit you're suppose to look at Heavy Rain for answers!

hmmm even if this was a real question theres not enough information in this problem to solve it.....so yeah poor shaun

Ask a math question!

Understanding the unit circles and reference angles steps below

•  First you Find the exact trigonometric function values for angles that measure 30°, 45°, and 60° using the unit circle.
•  Then you Find the exact trigonometric function values of any angle whose reference angle measures 30°, 45°, or 60°.
•  Lastly Determine the quadrants where sine, cosine, and tangent are positive and negative.

yes i have a vision you want me to tell you what two plus two is PHYCIC!!

ps dont know if i spelled that right lol

inverse operation is the operation that reverses the effect of another operation like for example addition can be countered with subtraction and vice versa.

sin(2u) = 2sin(u)cos(u)

sin(2sin^-1(x)) = 2sin(sin^-1(x))cos(sin^-1(x)) = 2xcos(sin^-1(x))

let y = sin^-1 x
x =siny

sin^2(y) = 1- cos^2(y)

cos^2(y) = 1 - sin^2(y)
cos^2(y) = 1 -x^2 >= 0 ( since anything^2 is always positive)

+/-cos(y) = sqrt(1-x^2)



sin(2sin^-1(x)) = 2sin(sin^-1(x))cos(sin^-1(x)) = 2xcos(sin^-1(x)) =+/- 2xsqrt(1-x^2)



Hopefully I didn't mess up somewhere.

The total bill for a dinner (excluding tax) is $50.00. If you leave an 18% tip, you will leave with less then you walked in with. I mean really why cant math be that simple it didnt ask for a specific number right????

.....Hungry.......

OK, seriously....we have

$50(1.18) =   $59.00

OK...so basically...one angle is 2.5 times as large as the other. Let's call the smaller angle "x" and the larger angle "2.5x."  And since they're complementary, they sum to 90 degrees.

So we have

x + 2.5x = 90

3.5x = 90   So x ≈ 25.7°   and 2.5x ≈ 64.3°

And

25.7° + 64.3° = 90°

Let's divide these first, before we take any roots...so we have

(24x^5y^2) / (3x^2y) =

8*x^3*y  and taking the cubed root, we get

(8*x^3*y)^(1/3)  =   2x(y)^(1/3) .......... so, only "y" remains under the cubed root.

[Note that we are implying that neither x nor y = 0 in the division !!]

OK...let's call the number of boxes he bought holding 7 cards, x. And let's call the number of boxes he bought holding 9 cards, y.

So we have

x + y = 17    (A)

And , the number of cards in each box type, times the number it holds added together = 135 

So we have

7x + 9y = 135   and

x +  y   =   17      By multiplying the bottom equation on both sides by -7, we can "eliminate" x. So we have

7x + 9y =    135 

-7x - 7y =  -119    And we get

2y = 16   So

y  = 8      And substituting this into (A), we have

x + 8 = 17   

So x  = 9

So he bought 9 boxes of 7 cards and 8 boxes of 9 cards = 135 cards

.........you know reinout i.....need to save my brain power for questions on the forum ill come back later.....maybe

its the oppisite side over the adjacent side or

when it said it came in boxes of 7 it means theres 7 cards in the box right?

Shawn bought boxes of thank you cards and get well cards. The thank you cards came in boxes of 7 and the get well cards came in boxes of 9. Shawn bought 17 boxes and got a total of 135 cards. How many boxes of each type of card did he buy?
