what is revolution in trigonometry

To measure an angle we shall use two kinds of units, the degree unit and the radian unit. A degree(Sexagesimal system) is defined to be an angle formed by half-line (or a ray) rotated about its end point (1/360) of a complete revolution. Types of Angles: Acute angle, Obt..

Question: The wheel of railway carriage is 90 cm in diameter and makes 3 revolutions in a second. How fast is the train moving? Answer: = 30.55 km/hr Note: 1m = 100cm 1km = 1000m = (1000)(100) = 100000 cm..

is that branch of mathematics which deals with the measurement of sides and angles of triangles. The word, trigonometry is derived from Greek, which means the measure of triangles. This subject was originally developed to solve problems in astronomy and geometry. In recent times, the su..

Trigonometry - With trigonometry we can find the height of a building or the width of a river without actually climbing or crossing. Certain basic definitions are necessary to further develop this subject. The ratios of two sides of a triangle are taken. There are six possible c..

(i) Sin q means a particular ratio. It is not sin multiplied by q . (ii) For trigonometrical ratios, short form T-ratios will be used. (iii) In right angled triangles T-ratios are obtained only for acute angles. (iv) T-ratios depend on only the magnitude of the angles and..
