now do it on the calc on the home page.

I like the way you have done that with a little computer program. I assume that is how you did it.

danemathesius was right the fist time

The number in the brackets must be between -1 and +1 (inclusive)

tan-1 is the same as atan   

Come on robtre,

You can find something more productive to do with your time than this.  :)

Newton's method

You are probably supposed to know the formula but I can't remember formulas so I work it out ever time.

$$$Remember, the gradient of the tangent at $x=x_1 $ is given by$ f'(x_0)\\
so\\\\
f'(x_0)=\frac{f(x_0)-0}{x_0-x_1}\\\\
f'(x_0)=\frac{f(x_0)}{x_0-x_1}\\\\
x_0-x_1=\frac{f(x_0)}{f'(x_0)}\\\\
-x_1=-x_0+\frac{f(x_0)}{f'(x_0)}\\\\
x_1=x_0-\frac{f(x_0)}{f'(x_0)}\\\\
$Now you have the formula$\\\\
\boxed{x_1=x_0-\frac{f(x_0)}{f'(x_0)}}\\\\$$

1-x-tan x = 0 starting at x0 = 0.5 

Let

$$\\f(x)=1-x-tanx\\
f'(x)=-1-sec^2x\\\\
f(0.5)=1-0.5-tan0.5\\
f(0.5)=0.5-0.546\\
f(0.5)=-0.046\\\\
f'(0.5)=-1-sec^2(0.5)\\
f'(0.5)=-1-(1/cos^2(0.5))\\
f'(0.5)=-2.298\\
so\\
x_1=0.5-\frac{f(0.5)}{f'(0.5)}\\\\
x_1=0.5-\frac{-0.046}{-2.298}\\\\
x_1=0.480$$

I have applied newtons method just once.

If you want more accuracy you can apply it again and again until you are happy. :)

1. Hold Shift and click on tan-1

2. Click on 2nd, then click on tan-1.

Hope it Helped!

You know it is 7.

It's not possible with exactly 10 numbers, but possible with less (22 solutions):

0 one 0 three 6 five 1 seven

0 one 1 three 4 five 2 seven

0 one 2 three 2 five 3 seven

0 one 3 three 0 five 4 seven

0 one 4 three 5 five 0 seven

0 one 5 three 3 five 1 seven

0 one 6 three 1 five 2 seven

1 one 0 three 3 five 3 seven

1 one 1 three 1 five 4 seven

1 one 2 three 6 five 0 seven

1 one 3 three 4 five 1 seven

1 one 4 three 2 five 2 seven

1 one 5 three 0 five 3 seven

2 one 0 three 0 five 5 seven

2 one 0 three 7 five 0 seven

2 one 1 three 5 five 1 seven

2 one 2 three 3 five 2 seven

2 one 3 three 1 five 3 seven

3 one 0 three 4 five 2 seven

3 one 1 three 2 five 3 seven

3 one 2 three 0 five 4 seven

4 one 0 three 1 five 4 seven

4p + 5 - 7p = -1

First combine the variable terms:

(4p - 7p) + 5 = -1

-3p + 5 = -1

Then subtract 5 from both sides to isolate the variable:

-3p = -6

Now divide both sides by -3 to get p:

p = -6/-3

p = 2

That depends on what the question is specifically.

It could be read as simply 2a³, or  (2a)³ , where it would simplify to 8a³.

$${\sqrt{{\mathtt{441}}}} = {\mathtt{21}}$$

*While -21 is also a square root of 441, the principal square root is positive 21.

Force=mass * acceleration

In order to find acceleration you would need to be given Force AND mass

You are correct, how are we to prove you wrong when you are right -,-

wait what? how do you multiply the 3-7 i still dont get it....

its still me btw

first you multiply the 3-7 over to the other side, and then distribute, so you have p=-6+14, which reduces to p=8.

except if there is an amplitude change

because sine is never greater than one. 

$${\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}$$         

$${\mathtt{\,-\,}}{\mathtt{19}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}} = -{\mathtt{16}}$$

$${\mathtt{\,-\,}}{\frac{{\mathtt{16}}}{{\mathtt{2}}}} = {\mathtt{x}}$$

$${\mathtt{x}} = -{\mathtt{8}}$$

please help me 😭😭😭😭😭
