- Finding an Angle in a Right Angled Triangle - Math is Fun
Step 2 Use SOHCAHTOA to decide which one of Sine, Cosine or Tangent to use in this question Step 3 For Sine calculate Opposite Hypotenuse, for Cosine calculate Adjacent Hypotenuse or for Tangent calculate Opposite Adjacent
- Sine, Cosine and Tangent - Math is Fun
Good calculators have sin, cos and tan on them, to make it easy for you Just put in the angle and press the button But you still need to remember what they mean! In picture form: Practice Here: Sohcahtoa How to remember? Think "Sohcahtoa"! It works like this: You can read more about sohcahtoa Remember it, as it may help in an exam !
- Finding a Side in a Right-Angled Triangle - Math is Fun
Step 2 Use SOHCAHTOA to decide which one of Sine, Cosine or Tangent to use in this question Step 3 For Sine write down Opposite Hypotenuse, for Cosine write down Adjacent Hypotenuse or for Tangent write down Opposite Adjacent
- Force Calculations - Math is Fun
We can use trigonometry to solve it Because it is a right-angled triangle, SOHCAHTOA will help For the Beam, we know the Adjacent, we want to know the Opposite, and "TOA" tells us to use Tangent: tan (60°) = Beam 785 N Beam 785 N = tan (60°) Beam = tan (60°) × 785 N Beam = 1 732 × 785 N = 1360 N
- Unit Circle - Math is Fun
Example: sin (30°) Sine: soh cahtoa sine is opposite divided by hypotenuse sin (30°) = opposite hypotenuse = 1 2
