Trigonometric Identities Cheat Sheet Having a comprehensive cheat sheet can be immensely helpful in simplifying expressions, solving equations, and understanding the properties of trigonometric functions. below are some essential trigonometric identities: 1. pythagorean identities: sin²θ cos²θ = 1. 1 tan²θ = sec²θ. 1 cot²θ = csc²θ. 2. Symbolab trigonometry cheat sheet basic identities: (tan )=sin(𝑥) cos(𝑥) (tan )= 1 cot(𝑥) (cot )= 1 tan(𝑥)) cot( )=cos(𝑥) sin(𝑥) sec( )= 1. Trig cheat sheet definition of the trig functions right triangle definition for this definition we assume that 0 2 p <<q or 0°<q<°90. opposite sin hypotenuse q= hypotenuse csc opposite q= adjacent cos hypotenuse q= hypotenuse sec adjacent q= opposite tan adjacent q= adjacent cot opposite q= unit circle definition for this definition q is any. 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.
