1. given:
csc(x) + sin(x)
2. definition of csc(x) :
1/sin(x) + sin(x)
3. combining fractions with a common denominator:
(1 + sin²(x))/sin(x)
4. expanding 1 = cos²(x) + sin²(x) :
(cos²(x) + sin²(x) + sin²(x))/sin(x)
5. simplifying:
(2 sin²(x) + cos²(x))/sin(x)
6. employing the same identity as in (4) :
(2 (1 - cos²(x)) + cos²(x))/sin(x)
7. expanding 2 (1 - cos²(x)) :
(2 - 2 cos²(x) + cos²(x))/sin(x)
8. simplifying:
(2 - cos²(x))/sin(x)

When two numbers have a number in common for both that can be multiplied to get both numbers
Answer:
Step-by-step explanation:
first you have to see itis an arithmetic or geometric sequence.
then find common difference(for A.P) or common ratio (for G.P)
c.d .=an-an-1
c.r. =an/an-1
1.G.P.
2. A.P
3.G.P
3,5,25/3,125/9,...
c.r.=5/3
or (25/3)/5=25/(3*5)=5/3
or 125/9÷25/3=125/9×3/25=(125×3)/(9×25)=5/3
