If you are trying to find a zero of xcos(x)-1/x you should note that there are an infinite number of them - see the graph below.

There is no solution at 5.166 radians!

$${\mathtt{5.166}}{\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{cos}}{\left({\frac{{\mathtt{5.166}}{\mathtt{\,\times\,}}{\mathtt{180}}}{{\mathtt{\pi}}}}\right)}{\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{\mathtt{5.166}}}} = {\mathtt{2.070\: \!241\: \!313\: \!464\: \!202\: \!4}}$$

I don't know if you can see the picture, but it was a graph

You're probably asking why this is so...

Consider some helium-filled balloons that have a lead weight attched to them. The balloons want to "rise" in a "positive" direction,  and the lead weight wants to pull the balloons in a "negative" direction - "downward."

What happens when we "subtract" the "negative,"  i.e., get rid of the lead weight??"  The balloons rise !! Thus, "taking away" a negative from a positive gives us a "larger" positive !!!

Remember it like this.......

Cutting away the weight - subtracting a negative from a positive - makes the balloons rise higher - the balloons get more "positive."

This is my answer, compleatly diffrent from yours for x^2+7x+53=11/3, which according to the calculator yealds {}:

Here you go......

whole number

Let's break this down

We can write "what percent" as.....   x/100

"Of 12" means to multiply by 12

"Is 18" means "equal to 18" or   "= 18"

So we have

(x/100) ( * 12)  (= 18)     ......so.......  

x/100 * 12  =  18        divide both sides by 12

x/100  =  18/12           express 18/12 as a decimal = 1.5

x/100 = 1.5                 multiply both sides by 100

x =   150

So... x/100.....  =   150/100  = 150%

So 18 is 150%  of 12

Put the calculator in radian mode at the bottom left.

Then just type in "sin(7*pi/18)" and hit the " = " button.

The 100th decimal digit is 9......you can see it here:

There will be 7 terms in this expansion

The fourth term term is the middle term and is given by:

C(6,3)*(3x^2)^3*(-2y)^3 =

20 * (27x^6) * (-8y^3)  =

-4320 x^6 y^3

$$y = 2 + 3 sin \frac{1}{2}(x-pi)$$

Let's take this by parts........

The "2" shifts the basic sine graph "up" 2 units.

The "3" increases the amplitude of the basic graph by a factor of 3

Using the "1/2" we can find the period of the function, thusly:

(1/2)x = 2pi       solving for x gives us the period

x = 4pi    ..... so the "1/2" doubles the period of the normal sine function

The (x - pi)  shits the graph to the right by "pi" units

Here are the graphs of the normal sine function and our function on the same axis

 Hope that helps some.......

Multiply $1813 by 30% in decimal form, which is 0.30. 

$${\mathtt{1\,813}}{\mathtt{\,\times\,}}{\mathtt{0.3}} = {\frac{{\mathtt{5\,439}}}{{\mathtt{10}}}} = {\mathtt{543.9}}$$

So 30% of 1813 is 543.9 :D

ya ya very funny ! 

Wait... I thought it was 12.

hey , why dont u check on a website named ;

algebra-class.com solving literal equations 

i havent tried it but i think u may get some help !
