Answer:
1 1/4 is the answer
Step-by-step explanation:
Hope this helps :))
The Taylor series is defined by:

Let a = 0.
Then its just a matter of finding derivatives and determining how many terms is needed for the series.
Derivatives can be found using product rule:

Do this successively to n = 6.

Plug in x=0 and sub into taylor series:

If more terms are needed simply continue the recursive derivative formula and add to taylor series.
Answer:
Is there a choice D in this because A, B and C are all incorrect answers
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
A. is the only correct solution to this question because you can also see that if we take 8 and divide this by 32 we get 1/4, so we know it is true.
Answer:

Step-by-step explanation:
22.5 degrees is half of 45 degrees (special angle for which we know exactly the value of all three basic trigonometric functions (sine, cosine, and tangent).
So we start recalling the formula for tangent of a half angle: 
We need just the values of:

and of

to answer the question. Then, we use those values in the original formula for tangent of a half angle:
