Ah, I now get it. Thanks, kitty<3

For example, DragonSlayer, suppose you want to use the inverse sine. The button that shows up on the calculator's home screen would be "sin".

To get the inverse sine (also caled arcsine) you would first press the "2nd" button in the top left corner. (See it?) Then you would press the button where "sin" had been. It now shows up as "asin", the inverse sine.

A trapezoid is a quadrilateral with only one pair of parallel sides.

x + y = sqrt(x^2+y^2)

x and y could be: 0 and any real number.

If x or y (let's say x) is 0, the equation would be:

0 + y = sqrt(0^2 + y^2)

Which simplifies to:

y = sqrt(y^2)

The sqrt and ^2 cancel out:

y = y

When you have an equation that simplifies to something equals itself, the solution would be all real numbers.

And Rosala, I hope you meant for Anonymous to graph the equation.

If you graph the equation on the calculator, it comes out as a straight line, with the y at 0. This shows that y  (or x) is 0 and x (or y) is all real numbers.

The only answer is x=0.

The answer is 101 and 1/2.

What button, kitty<3?

Press "2nd", then press the button. The inverses will pop up.

If you mean what 100 and 3/2 equals, Enter it as 100 + (3/2)

$${\mathtt{100}}{\mathtt{\,\small\textbf+\,}}\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right) = {\frac{{\mathtt{203}}}{{\mathtt{2}}}} = {\mathtt{101.5}}$$

It is 100 3/2

First off, do you mean 100 and 3/2, or 100 times 3/2, or something totally different?

Verify cot(x) * sec(x) = csc(x)

cot(x) = 1/tan(x)

tan(x) = sin(x)/cos(x)

So cot(x) = 1/ sin(x) * cos(x)

And sec(x) = 1/cos(x)

So the whole equation is:

1/ sin(x) * cos(x) * 1/cos(x) =csc(x)

The cos(x)  and 1/cos(x) cancel out:

1/sin(x) = csc(x)

csc(x) is the same as 1/sin(x):

csc(x) = csc(x)

30 es tu respuesta.

x=-(((4*y-8)/5)) is your answer.

Your answer is {x=-((1/3)), x=(3/2)}.

15 is the answer is the answer.

Thanks Melody. That was really nice.

38 is the only answer. This, ^, does not work on the calculator when I wrote ^2

Si. kitty<3 esta correcto. 5x5 es 25. 25 es tu respuesta.

Yes. I think that Anonymous is right. Only 0 and -49 can be tha answer.

20.156 is bigger than 20.1557. If you still don't get it, be free to ask me.

First, you put the numbers like this. 

After that, you look at the number after 8.

Numbers below 5: Number 8 stays the same.

Numbers 5 and up: Number 8 goes up one.

So, the answer is 3.429 when 3.4285 is rounded.

The answer is 56.5. kitty<3 was right.

Yes you are right it can be solved easily enough but I still got it wrong. I checked my maths a few times. I think it is calculator input.
