✓TRIGONOMETRY is an important branch of MATHEMATICS. The word trigonometry has been derived from three Greek words TREI (three) GONI (angles) METRON ( measurements) so trigonometry means measurements of triangles ✓Angle: Two rays with a common starting point form an angle *Initial side: The first ray of an angle is called initial side *Terminal side: The second ray of an angle is called terminal side *Vertex: The common point of contact of rays is called vertex *Notation: Angle is denoted by Greek letter alpha, beta, gamma or theta ✓ Quadrantal Angle: If terminal arms of an agle falls on x axis or y axis then angle is called quadrantal angle Examples: 0°,90°,180°,270°,360° and 540° are Quadrantal Angles ✓ Acute Angle: The angle less than 90° is called acute angle Examples: 20°,30°,44°,60°,70° and 85° are acute angles ✓ Allied Angles: The angles of the form 90°+/- A ,180°+/- A, 270°+/- A and 360° +/- A are called allied angles wher A is any acute angle Examples: 375°,480° ,120° and 600° are allied angles ✓Angle in standard position: An angle is said to be in standard position if its initial side is along +ve x axis and its vertex at origin Examples: 45°,60° ,75° and 150° are angles in standard position Units of measurements of angle: ✓Circular System: The system of measurement in which angle is measured in radians is called circular system Example: pi/4 ✓ One Radian: The circular measure of an angle is called one Radian if arc length of the circle Equal to radius of the circle ✓Sexagesimal System: The system of measurement in which angle is measured in degree, minutes or second is called sexagesimal System ✓ One Degree : If we divide circumference of the circle into 360 equal parts then the angle subtended from the centre of the circle by one part or by an arc is called one degree ✓ One Minute: The 60th part of one degree is called one minute ✓ One Second: The 60th part of one minute is called one second or The 3600th part of one degree is called one second ✓ Graph of a function and its inverse is reflecting about the line y = x Table Values of Trigonometric Functions: ✓sinO°= 0 ,sin30° = 1/2 , sin45°= 1/ root 2 , sin60°=root3/2 ,sin90°=1 ✓cosO°= 1 ,cos30° = root3/2 , sin45°= 1/ root 2 , cos60°=1/2 ,cos90°=0 ✓tanO°= 0, tan30° = 1/root3 , tan45°= 1, tan60°=root 3 ,tan90°=undefined 00:00 Introduction 00:12 A-o-A my dear and sweet subscribers wellcome to Shah Hussain Maths Online 00:29 MCQS # 1 02:20 MCQS # 2 04:00 MCQS # 3 06:49 MCQS # 4 09:28 MCQS # 5 11:47 MCQS # 6 12:56 MCQS # 7 13:34 MCQS # 8 14:06 MCQS # 9 16:10 MCQS # 10 17:39 MCQS # 11 20:41 MCQS # 12 23:43 MCQS # 13 25:08 MCQS # 14 27:44 MCQS # 15 29:00 Plx like, subscribe, press the bell,comments and share, Thanks For more videos visit to play list: Ecat Lecture # 01 : 👉 • Entry Test Past Papers Mcqs | Functions an...
