4th quadrant is positive x (cos) and negative y (sin)
Use the Pythagorean Theorem to calculate the value of y (sin).
x² + y² = c²
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
Since the y-value is negative in the 4th quadrant, then y = -12
Example:
12+24
GCF:
12: 1,2,3,4,6,12
24: 1,2,3,4,6,8,24
Common factors: 1,2,3,4,6
Greatest factor: 6
Divide:
12 divided 6= 2
24 divided 6= 4
12+24= 6x(2+4)
We have been given that a geometric sequence's 1st term is equal to 1 and the common ratio is 6. We are asked to find the domain for n.
We know that a geometric sequence is in form
, where,
= nth term of sequence,
= 1st term of sequence,
r = Common ratio,
n = Number of terms in a sequence.
Upon substituting our given values in geometric sequence formula, we will get:

Our sequence is defined for all integers such that n is greater than or equal to 1.
Therefore, domain for n is all integers, where
