What is the formula for SOH CAH TOA?
SOH: Sin(θ) = Opposite / Hypotenuse. CAH: Cos(θ) = Adjacent / Hypotenuse. TOA: Tan(θ) = Opposite / Adjacent.
How do you use Soh?
The hypotenuse is always opposite the right angle. The sine of an angle is equal to the side opposite the angle divided by the hypotenuse….Sohcahtoa Calculator.

How do you find the missing side length of a triangle using trigonometry?
Right Triangles and the Pythagorean Theorem
- The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
- The side opposite the right angle is called the hypotenuse (side c in the figure).
How do you do trigonometry formulas?
By using a right-angled triangle as a reference, the trigonometric functions and identities are derived:
- sin θ = Opposite Side/Hypotenuse.
- cos θ = Adjacent Side/Hypotenuse.
- tan θ = Opposite Side/Adjacent Side.
- sec θ = Hypotenuse/Adjacent Side.
- cosec θ = Hypotenuse/Opposite Side.
- cot θ = Adjacent Side/Opposite Side.
How do you memorize SOH CAH TOA?
Note: Round your answers to 3 decimal places, when neccessary. SOH CAH TOA is an acronym used to memorize the three trigonometric ratios . Indeed simply say “SOH CAH TOA” a few times and you’ll remember those “words”.
What does SOH CAH TOA stand for?
SOH CAH TOA is an acronym used to memorize the three trigonometric ratios . Indeed simply say “SOH CAH TOA” a few times and you’ll remember those “words”. Watch the following Tutorial to learn how to use it.
What are the three basic trig ratios used for missing sides?
It’s a mnemonic device to help you remember the three basic trig ratios used to solve for missing sides and angles in a right triangle. It’s defined as: SOH: Sin (θ) = Opposite / Hypotenuse. CAH: Cos (θ) = Adjacent / Hypotenuse. TOA: Tan (θ) = Opposite / Adjacent.
How do you calculate sin cos and Tan?
They are often shortened to sin, cos and tan. The calculation is simply one side of a right angled triangle divided by another side we just have to know which sides, and that is where “sohcahtoa” helps. For a triangle with an angle θ , the functions are calculated this way: Sine: soh… s in ( θ) = o pposite / h ypotenuse.
