Answer:
Option D) is true about median
Step-by-step explanation:
We are given the following information in the question:
Median:
- The median is the middle number or the center of the data when the data is sorted in either ascending or descending order.
- The median is not affected by the presence of any outliers since the data is sorted.
Option A) Medians are not affected by the outliers
Option B) Medians can only be calculated when the data is sorted.
Option C) This is a false statement about the medians.
Option D) True
When there are even number of observations, the median is the mean of the two middle numbers.
Answer:
sin t =
cos t =
tan t =
csc t =
sec t =
cot t =
Step-by-step explanation:
In the unit circle:
- x-coordinate of a point on the circle represents cosine the angle between the + ve part of x-axis and the terminal side which joins the center of the circle and this point
- y-coordinate of a point on the circle represents sine the angle between + ve part of x-axis and the terminal side which joins the center of the circle and this point
In the attached figure
∵ t represents the angle between + ve part of x-axis
and the terminal side drawn from the center of the circle to
point P
∴ The coordinates of point P are (cos t , sin t)
∵ The coordinates of P are ( ,
)
∴ sin t =
∴ cos t =
∵ tan t =
- Substitute the values of sin t and cos t
∴ tan t =
- Multiply up and down by 5 to simplify the fraction
∴ tan t =
∵ csc t =
- Reciprocal the value of sin t
∴ csc t =
∵ sec t =
- Reciprocal the value of cos t
∴ sec t =
∵ cot t =
- Reciprocal the value of tan t
∴ cot t =
