That phrase helped to remember the order; sine, cosine and tangent. O Oscar Sine =  =  H Hit A A Cosine = = H Homerun O Over Tangent =  =  A Alaska To find the reciprocal functions, just remember Sin theta goes with the co secant cosine goes with the secant tangent goes with the co tangent. Each pair has a "co." For example, sin does not have a "co" so the only logical one to pick is the cosecant as the reciprocal function. Thus: H Cosecant =  O H Secant =  A A Cotangent =  O
