Consider SOH - CAH - TOA, what does CAH stand for?

• sin⁡θ=oppositehypotenuse\sin\theta=\frac{opposite}{hypotenuse}

  sinθ=hypotenuse

  
  

  opposite

  ​

• cos⁡θ=adjacenthypotenuse\cos\theta=\frac{adjacent}{hypotenuse}

  cosθ=hypotenuse

  
  

  adjacent

  ​

• tan⁡θ=oppositeadjacent\tan\theta=\frac{opposite}{adjacent}

  tanθ=adjacent

  
  

  opposite

  ​

• tan⁡θ=sin⁡θcos⁡θ\tan\theta=\frac{\sin\theta}{\cos\theta}

  tanθ=cosθ

  
  

  sinθ
