They are sin=opposite/hypotenuse cos=adjacent/hypotenuse tan=opposite/adjacent  Proportionality constants are written within the image: sin θ, cos θ, tan θ, where θ is the common measure of five acute angles. In mathematics, the trigonometric  The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions. Their usual abbreviations are sin(θ)   sin(theta) = a / c. ### 12. cos( ) = cos cos sin sin : 13. tg( ) = tg tg 1 tg tg : 14. ctg( ) = ctg ctg 1 ctg ctg : 15. sin2 = 2sin cos : 16. cos2 2= cos sin2 : 17. tg2 = 2tg

In geometric applications, the argument of a trigonometric function is generally the measure of an angle.For this purpose, any angular unit is convenient, and angles are most commonly measured in conventional units of degrees in which a right angle is 90° and a complete turn is 360° (particularly in elementary mathematics).
