Trigonometry Formula Ratios And Identities вђ Artofit Cot θ = 1 tan θ. sin θ = 1 cosec θ. cos θ = 1 sec θ. tan θ = 1 cot θ. pythagorean identities. according to the pythagoras theorem, in a right triangle, if ‘c’ is the hypotenuse and ‘a’ and ‘b’ are the two legs then c2 = a2 b2. we can obtain pythagorean identities using this theorem and trigonometric ratios. Double angle and half angle formulas 26. sin(2 ) = 2 sin cos 27. cos(2 ) = cos2 sin2 28. tan(2 ) = 2 tan 1 2tan 29. sin 2 = r 1 cos 2 30. cos 2 = r 1 cos 2 31. tan 2 = 1 cos sin = sin 1 cos 32. tan 2 = r 1 cos 1 cos other useful trig formulas law of sines 33. sin = sin = sin law of cosines 34. a2 = b2 c2 2 b c cos b2 = a2 c2 2 a c cos c2 = a2. Trigonometric ratios identities. several trigonometric ratios identities make our calculations simpler such as: sin 2 θ cos 2 θ = 1; 1 tan 2 θ = sec 2 θ; 1 cot 2 θ = cosec 2 θ; there are also some variations of the above 3 identities, which are nothing but rearranging the ones given above. trigonometric ratios of complementary. There are three pythagorean trigonometric identities in trigonometry that are based on the right triangle theorem or pythagoras theorem. sin 2 a cos 2 a = 1; 1 tan 2 a = sec 2 a; cosec 2 a = 1 cot 2 a; ratio trigonometric identities. the trigonometric ratio identities are: tan θ = sin θ cos θ; cot θ = cos θ sin θ.
