I'll take the picture.
(1+cos\theta)/(sin\theta)+(sin\theta)/(cos\theta)=\frac{cos\theta+1}{sin\theta{cos\theta}}
Multiply by sin\theta{cos\theta} to get:
(1+cos\theta)sin\theta=cos\theta+1, which means that sin\theta=1, like wtf?
I guess you got to this result.
Btw, if it's an equation you get that \theta=k\pi, for k integer.

Which of the following represents the sample space for flipping two coins?A
{HH, TT}

B
{H, T}

C
{HH, HT, TH, TT}

D
{HH, HT, TT}

Answers

C.  { HH, HT , TH, TT}

Step-by-step explanation:

Sample Space  of any event E is the set of all possible outcomes whenever  that event takes place.

Here, event E : Tossing 2 coins

Now, as we know, when an unbiased coin is tossed,

The total outcomes  = {Head, Tail}

So, when two coins are flipped, the total outcomes are  2 x 2  = 4.

Sample space   =  { Head Head, Head Tail, Tail Head, Tail Tail}

or, S  = { HH, HT , TH, TT}

3 (n+6) do I do 3xN=3n than 3x6=18 n=6?

Answers

yes because it's the distributive property. The distributive property is where you multiply whatever is in the parentheses to the number on the outside. For instance, 5(20+11)  to answer this, you set it up like this: 5(_+_) this mean that there are two in the answer. So 5*20 equals 100 and 5*11 equals 55 so to set it up, you do 100+55. To see it the answer is right, you say 5(_+_) and like the factoring to find the numbe is the greatest common factor. The GCF of 100 and 55 is 5 so 100 divided by 5 equal 20 and 55 divided by 11 equals 5 so there you go.
