SOHCAHTOA Calculator

This calculator makes use of the SOH.CAH.TOA mnemonic approach to clear up the edges and angles of a right triangle. It presents step-by way of-step calculations the usage of the SOHCAHTOA formula, which we are going to mention under.

what is SOHCAHTOA?

SOH CAH TOA is a mnemonic way used to do not forget the formulas for important trigonometric ratios such as sine (sin), cosine (cos), and tangent (tan). right here's what each letter inside the acronym stands for:

• S: Sine
• O: opposite side
• H: Hypotenuse
• C: Cosine
• A: Adjoining facet
• T: Tangent

It refers to which of the trig ratios can be used for finding lacking aspects and angles based at the formulas below.

SOH: (Sin (θ)) = opposite Hypotenuse

CAH: (Cos (θ)) = adjoining Hypotenuse

TOA: (Tan (θ)) = contrary adjoining

Even the sohcahtoa calculator implements these formulas to calculate missing aspects and angles.

How to without difficulty recall SOHCAHTOA?

It is simple to keep in mind the collection of Sin, Cos, and Tan. You want to strive memorable phrases which includes:

“Oscar Had A Heap Of Apples”

It implies to right attitude trig features as:

• Sin(θ) = Oscar / Had = Opposite ÷ Hypotenuse
• Cos(θ) = A / Heap = Adjacent ÷ Hypotenuse
• Tan(θ) = Of / Apples = Opposite ÷ Adjacent

The way to resolve missing sides the use of SOHCAHTOA?

There are steps to exercise session the unknown facets of a proper-angled triangle:

• listing out the perimeters of the right-angled triangle
• Pick out the trig ratio this is about the statistics we must have
• Positioned the values into the trigonometric feature and find the lacking facet

Example:

we've got a proper triangle with the subsequent measurements:

• Hypotenuse = 10 cm
• Angle α = 45°

Locate the lacking aspect this is contrary to the acute perspective.

Solution:

we are looking for the alternative facet with the aid of having the hypotenuse, so use the SOH method. for this reason, substitute the values to locate the missing aspect.

Sin(45°) = Opposite / 10 cm

We also know that Sin(45°) is a fixed value (√2/2 or 0.707).

0.707 = Opposite / 10 cm

Now, to find the lacking contrary aspect, multiply both aspects of the equation by way of 10 cm.

Opposite = 0.707 * 10 cm

Opposite = 7.07 cm
