sin n pi formula On a unit circle x x coordinate of any point on the circle is given by cos cos and y y coordinate is given by sin sin Now sin n sin n where n 0 1 2 3 n 0 1 2 3 is always the X axis and on X axis we have y 0 y 0 and cos n cos n assumes x
In trigonometry formulas we will learn all the basic formulas based on trigonometry ratios sin cos tan and identities as per Class 10 11 and 12 syllabi Also find the downloadable PDF of trigonometric formulas at BYJU S The Trigonometric Identities are equations that are true for Right Angled Triangles If it isn t a Right Angled Triangle use the Triangle Identities page Each side of a right triangle has a name Adjacent is always next to the angle And Opposite is opposite the angle

Basic trig identities are formulas for angle sums differences products and quotients and they let you find exact values for trig expressions Trigonometric identities are equalities involving trigonometric functions An example of a trigonometric identity is sin 2 theta cos 2 theta 1 sin2 cos2 1 In order to prove trigonometric identities we generally use other known identities such as Pythagorean identities
The Law of Sines or Sine Rule is very useful for solving triangles a sin A b sin B c sin C It works for any triangle And it says that When we divide side a by the sine of angle A it is equal to side b divided by the sine of angle B and also equal to side c To solve a trigonometric equation we need the following preliminary knowledge If sin theta sin alpha then theta n pi 1 n alpha Thus if n is odd theta 2m 1 pi alpha and if n is even theta 2m pi alpha
