Answer:
Step-by-step explanation:
Given
Sequence = Consecutive Odds
Required
The sum of the terms
A sequence of odd number has a difference of 2. So, the sequence is represented as:
Add up all terms in the sequence
Angles could be expressed in degrees or in radians. The relationship between the two could be easily explained by illustrating a circle. A semi-circle has a total angle of 180°. This is equal to a π radians. So if the angle is π/2, in degrees, that would be 180/2 = 90°.
Then, determining the cosine 90° in a calculator would yield an answer of zero.
Answer:
The opposite of a positive number is a negitive number and vice versa!
