Answer:
cos θ = 1/2
Step-by-step explanation:
4 cos θ + 4 sin² θ = 5
Use Pythagorean identity.
4 cos θ + 4 (1 − cos² θ) = 5
4 cos θ + 4 − 4 cos² θ = 5
0 = 4 cos² θ − 4 cos θ + 1
0 = (2 cos θ − 1)²
0 = 2 cos θ − 1
cos θ = 1/2
<h3>ANSWER</h3>
first is the geometric series
<h3 /><h3>EXPLANATION</h3>
a geometric series is a sequence of numbers whose first term is non zero and each of the succeeding terms is equal to the Prcedding term multiply by a constant number.
if a = first term
and constant number = d
then
GP is given by
a,a r , a r^2 ,a r^3 .............and so on
in first
a = 1/2
and d = 1/2
and hence it is an GP
