I'm guessing S^20 is actually referring to the 20th partial sum
, with
in the arithmetic case, and
in the geometric case.
(a) Combining like terms, we have
and invoking the formula
we end up with
(b) Multiply
by 1.1, then subtract this from
:
In place of t, or theta, I'm going to utilize x instead. So the equation is -3*cos(x) = 1. Get everything to one side and we have -3*cos(x)-1 = 0
Let f(x) = -3*cos(x)-1. The goal is to find the root of f(x) in the interval [0, 2pi]
I'm using the program GeoGebra to get the task done of finding the roots. In this case, there are 2 roots and they are marked by the points A and B in the attachment shown
A = (1.91, 0)
B = (4.37, 0)
So the two solutions for theta are
theta = 1.91 radians
theta = 4.37 radians
Answer:
4 over 5
Step-by-step explanation:
its 4 over 5 because your going to get a decimal and the other answers you will get a integer which the question isnt asking for so the answer is 4 over 5
Answer:
1
Step-by-step explanation:
it is an identity. hope it helps
