Consider a triangle ΔABC, where sides AB, BC and angle ∡C are given.
Angle ∡C is the angle opposite of side AB.
It says that the given side opposite the given angle is less than the other given side. It means AB < BC.
It says that the ratio of the longer side to the shorter side, multiplied by the sine of the angle opposite the shorter side, is less than 1. It means
· sin(C) < 1
We know about Law of Sines of Triangle is given by :-
\\
We got sin(A) < 1, and BC > AB.
Therefore, angle ∡A could be either acute or obtuse angle.
So, There will be two solutions for the angle ∡A.
⇒ option D is the final answer.
First we rewrite the expression correctly:
tn = ((-1) ^ n) * (n)
We now look for each of the terms:
t1 = ((-1) ^ 1) * (1) = - 1
t2 = ((-1) ^ 2) * (2) = 2
t3 = ((-1) ^ 3) * (3) = - 3
t4 = ((-1) ^ 4) * (4) = 4
The first four terms of the sequence are then:
-1, 2, -3, 4
Answer:
B.
-1, 2, -3, 4
