To explain an answer, sometimes a free-hand drawing is needed. If I draw a free-hand drawing on word page, how can I connect this page while answering on yahoo answers

Let c be the boundary of the region enclosed between y=x^2 and y=2x. Evaluate ∫ (6xy-y^2)dy by green’s theorem.

Use a double integral in polar coordinates to find the area of the region inside the circle r =1 and outside the cardioid r=1+cos(theta)

Approximate (1-x^2)^1/2 dx from 0 to 1 using the left end point right end point and mid it point approximation each with n=10 , n=20 , n=50 , n=100 sub intervals.

Find a non-zero value for the constant “k” so that

f(x)=(tan(kx))/x when x<0 and

f(x)=3x+2k^2 when x>0 and

the function is continuous at x=0

I have to solve the question by long division method of getting the sqr. How can I do it?

\how will we solve it?

Example: "when water is poured at sodium it shows burning"

At what distance(in kilometres) from the earth, the gravitational pull(force) becomes zero?

Which transparent chemical substance turns to coloured when dissolved in water and which coloured one became colourless in water?

We know that electric Power = voltage x current. so if voltage is increased the current will have to be decreased to keep the power constant. My question is how does change of voltage or current (separately) affect the appliance consuming electric power?

Many a time when solving a math or physics question, diagram is needed which I draw on MS Word or some time on MS Excel but that cannot be pasted on yahoo answer window because option of drawing is not available on the window. So how can I link the work done on MS Word or Excel etc to share with the others?

Let x=1

then x^2 =1.

Now x^2 - 1 = 0

or (x+1)(x-1)=0

Dividing both sides by (x-1) we get (x+1)(x-1)/(x-1)=0/(x-1) which gives x+1=0. Putting the value of x which was taken as 1 we see that 2=0 ???
