Consider the following statements: I. The trigonometric ratio can be measured by measuring the angles in circular system but not in centesimal system and sexagesimal system II. The trigonometric ratio can be measured by measuring the angles in circular system and centesimal system but not in sexagesimal system

Consider the following statements: I. The trigonometric ratio can be measured by measuring the angles in circular system but not in centesimal system and sexagesimal system II. The trigonometric ratio can be measured by measuring the angles in circular system and centesimal system but not in sexagesimal system Correct Answer Neither 1 nor 2

Given:

Concept Used:

Basic concept of trigonometric ratio and identities

Calculation:

The trigonometric ratio can be measured by measuring the angles in all the system given below

In sexagesimal system, we have 1 right angle = 90°

∴ 1° = 60'

 And 1' = 60"

In centasimal system, we have 1 right angle = 100g

∴ 1g = 100'

And 1' = 100"

In circular system, the unit of measurement is radian. Radian one radian is the measure of an angle Subtended at the center of a circle by an arc of length equal to the radius of the circle.

∴ Both statements are incorrect

Hence, option (4) is correct

Consider the following statements for dynamic characteristics of a measurement system: 1. Fidelity is defined as the degree to which a measurement system indicates changes in the measured quantity without any dynamic error. 2. Dynamic error is the difference between the true value of the quantity changing with time and the value indicated by the measurement system if no static error is assumed. 3. Measuring lag is the retardation in the response of a measurement system to changes in the measured quantity. Which of the above statements are correct?
