Step-by-step explanation:
From Trig
1 + tan²x = Sec²x
Also
Sec²x = 1/cos²x
Now
Cot²x = 1/tan²x = cos²x/sin²x
Putting all together
Cot²x(1+tan²x)
= Cot²x(sec²x)
= cos²x/sin²x(1/cos²x)
cos²x on the numerator and that one the denominator cancels out
we have
= 1/sin²x
From Trig
1/sin²x = cosec²x
So Our Answer = cosec²x.
-6 + 10 = 4
but you say the answer is 17?
okay, so let's assume you add 13 to the final answer
3 - 5 = -2
-2 + 13 = 11
This question doesn't make sense
Answer:
The terms listed are 8, 4, and 2 in that order. From what we can see, it is a geometric sequence whose next term is gotten by dividing the previous term by 2. The formula for finding the nth term of a geometric sequence is given as
, where
a = first term which is 8
r = common ratio, 1/2 or 0.5
n = is the term we're looking for, 5
Putting all these together into one solid equation, we have
8 *
=
8 *
=
8 * 0.0625 = 0.5
Therefore, the 5th term of the sequence is 0.5. Similar example can be seen here brainly.com/question/9300199
Hey!
You stuck?
Well here is some help!
The answer is 1.3 because 3 -3 is 0 and 2.7-1.4 =1.3
