Answer:
i cannot help you get the answer to the question without more information but i can explain how to solve it, what your question is, is called a "permutation"
Step-by-step explanation:
To calculate permutations, use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)! , an exclimation point means the factorial, say we need the factorial of 4, we would do this 4x3x2x1 go left to right, and it is not all at once. you multiply 4 times 3 which equals 12, then multiply 12 times 2... so on and so forth
Point-slope for a line is:
(y-y1)=m(x-x1) where (x1,y1)=(1,1) and m=6 so
y-1=6(x-1)
In order to prove
Let's write both sides in terms of 
only.
Let's start with the left hand side: we can use the formula for sum and subtraction of the sine to write
and
So, their multiplication is
So, the left hand side simplifies to
Now, on with the right hand side. We have
Now simply make this expression one fraction:
And as you can see, the two sides are equal.
