Angle Based on the above addition formulas for sin and cos, we get the following below formulas: sin(π/2-A) = cos A; cos(π/2-A) = sin A; sin(π-A) = sin A Important updates relating to your studies which will help you to keep yourself updated with latest happenings in school level education. Angle is a measure of rotation of a given ray about its initial point. The original ray is called the initial side and the final position of ray after rotation is called terminal side of the angle. (i) sin (x + y) = sin x cos y + cos x sin y These notes, during the exam time, will act as a ready referral to go through. or 1 radian = 57° 16′ 21″ (approx) Download free RD Sharma Solutions for questions given in all excercises relating to chapter Trigonometry...

Equation which involves trigonometric functions of unknown angles is known as the trigonometric equation. A solution of a trigonometric equation, involving ‘n’ which gives all solution of a trigonometric equation is called the general solutions. Solution of a Trigonometric Equation For general reduction, we have following rules, the value of trigonometric function for ($$\frac { n\pi }{ 2 } \pm \theta$$) is numerically equal to, An angle made up of the sum or difference of two or more angles is called compound angles.
