The value of csc theta is
It is important to note that the ratio for cot is given as;
Cot theta = adjacent/opposite
cosec theta = hypotenuse/opposite
If cot theta = 3/2, then
Adjacent = 3
Opposite = 2
Using Pythagoras theorem, we have
Hypotenuse square = opposite + adjacent square
Cosec theta =
Thus, the value of csc theta is

Answer:
Step-by-step explanation:
Given that,
...(1)
We need to find the value of .
Put n = 1 to find the first term.
Put n = 2 to find the second term.
Put n = 3 to find the third term.
Put n = 10 to find the tenth term.
It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :
We have, n = 10, a = 5 and
So,
So, the value of is equal to 280.
