(3, 1) because you would do the parenthesis part first (PEMDAS). 3+6=9, then 9x1=9
Your answer is 1/12
Hope it helps
The sum is the answer to an addition problem
Example : The sum of 4 and 2 : 4 + 2 = 8
Answer:
Square root of 15^2-9^2=12
square root 13^2-12^=5
hence cosθ = 5/13 not 13/5.
I guess the sequence is
which we can write as
converges if it is bounded and monotonic. Consider the function,
which has derivative
for all , so is monotonically decreasing on , and as we have
So we know that is monotonically decreasing and bounded below by .
To find the limit, we can also write
As , the rational terms vanish and we're left with
