sin(x)+tan(x)=sin(x)(......)

\(\sin{(x)} +\tan{(x)} \\ =\sin{(x)} + \frac{ \sin{(x)} } { \cos{(x)}} \\ =\sin{(x)}\cdot \left (1 + \frac{ 1 } { \cos{(x)}} \right) \\\)

32C5=32!/(32-5)!5!

\(32C5\\ =\binom{32}{5}\\ =\frac{32}{5}\cdot \frac{31}{4}\cdot \frac{30}{3}\cdot \frac{29}{2}\cdot \frac{28}{1}\\ =\frac{24165120}{120}\\ \mathbf{32C5=201376} \)

30!*2/20

\(30! \cdot \frac{2}{20} = 30! \cdot \frac{1}{10} = 30! \cdot \frac{1}{2\cdot 5} \)

sin(x)+tan(x)=sin(x)(......)

 = sec(x)+1

Do you want evaluated? Do you understand what the left and the right mean? Do you know what this (!) means? At any your answer is=201,376. Good luck.

In what temperature is the "Wind Chill Factor" calculated now? And what does V(temp) stand for?.
 

It most certainly is a repeating decimal!!.

csc 64°23'

i understand what to do when it says sin,cos,&tan but i dont know what to do when it says csc,sec, or cot

You simply have to remember the relationships between sine, cosine and tangent. The other three are the reciprocal of these 3 functions as follows:

csc=1/Sine, sec=1/Cosine, cot=1/Tangent

waat is 6.2 x 10 to the negative 12th power?

(6.2 X10)^-12, this simply means,

1 / ((6.2 X 10)^12)

=3.0995577 X 10^-22

Simplest answer: Use parentheses.

Ex: one-third minus two-fifths would be (1/3) - (2/5) = (-1/15),

And one-third times two-fifths would be (1/3) * (2/5) = (2/15).

You could also change the input on the site calculator to "Fractions" by clicking on the gray word "Scientific" (in the answer box) and selecting "Fractions" from the drop-down menu.

OK, Guest....that sounds plausible......

cos 64°45'   convert minutes to decimal degrees   →  45'  = .75 degrees

So

cos (64.75°)  = about 0.427

I assume this is:

((4-i)-(3+2i))^2     simplify

(1 - 3i)^2  =

(1 - 3i) (1 - 3i)  =

1 - 6i + 9i^2  =

1 - 6i - 9  =

-8 - 6i

CPhill: I assumed it to mean: 1/4 (9 x+5) = 0, hence the answer I gave.

((9*x+5)/4).....there is no question here.......!!!!

This can't be further simplified, either

Just plug in 3 in g, then x^2=3 X 3=9

Next 3+2 in g, the x^2=5 X 5=25.....and just follow this pattern.

Make sure there is another bracket before 4. If that' s the case, then your answer is=-8-6 i

Your answer is

=-5/9

The answer is=1000,000 X1000,000

=1,000,000,000,000=1 X 10^12

It's called a "TRILLION"

Your answer=7

(100,000 – X)/80,000 = 1.01 can someone explain how 1.01 is the answer?

(100,000- X)=1.01 X80,000

100,000 - X=80,800

X=100,000 - 80,800=19,200

X=19,200

(4/5) (-20) =

( 4 * -20) / 5  =

-80 / 5  =

-16

tan(135°)  = -1
