How do you set up the trigonometric ratio used to find the missing quantity?
To set up a trigonometric ratio for finding a missing quantity in a right triangle, first identify the relevant sides and angle. Use the appropriate trigonometric function: sine (opposite/hypotenuse), cosine (adjacent/hypotenuse), or tangent (opposite/adjacent) based on the given information. Write the equation by substituting the known values into the ratio, and then solve for the missing quantity.
What is the sin cos tan trick?
Sine is opposite side of angle over hypotenuse. Cosine is adjacent side of angle over hypotenuse. Tangent is the opposite side over the adjacent side.
How do you find sin?
Sin in mathemtics is correctly spelled as 'SINE'. The word 'sine' comes from Latin and means 'curve'. To find the 'sine' of an angle, use the eq'n Sin(Angle) = o(Opposite) / h(hypotenuse) So for any right-angled (90 degree) triangle , the 'hypotenuse' is the side opposite to the right angle. The 'opposite' is the side opposite to the angle in question. So for an example Sin(30 degrees) = 1/2 = 0.5 The 'opposite' side has a ratio length of '1' compared to the ;hypotenuse' side which will have a ratio length of '2'. Other Trigonometric functions are;- Cos ( Cosine = Complementary Sine) = adjacent / hypotenuse Tan = Tangent = opposite / adjacent.
Which correctly describes the tangent function?
opposite/adjacent :) apex
What are the trigonometric functions?
sine, cosine, tangent, cosecant, secant and cotangent.
The trigonometric ratio that compares the opposite side length to the adjacent side length is what?
tangent
What does socotoa mean?
It is an 'Aide memoire' to help with using the correct sides , with the correct function. . socatoa, becomes SOHCAHTOA ; SOH , CAH, TOA. SOH is Sin(angle) = Opposite/Hypotenuse. CAH is Cosine(Cos(angle)) = Adjacent/ Hypotenuse TOA is Tangent(Tan(Angle)) = Opposite / Adjacent.
What are the basic trigonometric ratios?
Sine(Sin) Cosine(Cos) Tangent(Tan) ---- -Sin of angle A=opposite leg of angle A / hypotenuse -Cos of angle A= Adjacent leg of angle A / Hypotenuse -Tan of angle A= opposite leg of angle A / Adjacent lef of angle A

What are some good examples of math acronyms?
If you study trigonometry you learn the definitions of the trigonometric functions by means of the acronym SOH CAH TOA which stands for sine: opposite over hypotenuse; cosine: adjacent over hypotenuse; tangent: opposite over adjacent. This is a very useful acronym.
The tangent of an angle equals the ratio of the what?
in a right trianlge the tangent is the ratio of Opposite/Adjacentcosine is Adjacent/Hypotenusesine is Opposite/Hypotenuse
What is sahcahtoa?
Sohcahtoa is an abbreviation (SOH) sine opposite hypotenuse (CAH) cosine adjacent hypotenuse (TOA) tangent opposite adjacent.
What is the equation for finding the sine and cosine and tangent of a triangle?
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
What is the formula for sine function?
In a right triangle, its Opposite/Hypotenuse I always use: Soh (sin, opposite/hypotenuse) Cah (cosine, adjacent/hypotenuse) Toa (tangent, opposite/adjacent) Hope this helped! :)
What are trigometric ratios?
The ratios pertaining to right angled triangles are called trigonometrical ratios.They are- sine x = Opposite side/Hypotenuse cosine x= Adjacent side/Hypotenuse tangent x= Opposite side/Adjacent side Cosecant x= Hypotenuse/Opposite side secant x= Hypotenuse/Adjacent side cotangent x= Adjacent side/Opposite side Here, x is one of the angles in the trangle except the right-angled one.
Values of the 6 trigonometric functions?
Sine Theta (sin θ) = opposite/hypotenuse = a/c Cosine Theta (cos θ) = adjacent/hypotenuse = b/c Tangent Theta (tan θ) = opposite/adjacent = a/b Cotangent Theta (cot θ) = adjacent/opposite = b/a Secant Theta (sec θ) = hypotenuse/adjacent = c/b Cosecant Theta (csc θ) = hypotenuse/opposite = c/a You may need to look on the link below for some sample calculations
How do you know which trigonometric ratio to use when finding the measure of an angle?
Apply the 'aide memoire'. Soh , Cah, Toa. To find the Sine you apply Soh ; so you need to known the lengths of the opposite and the hypotenuse. Cosine(Cos) you apply Cah ; so you need to known the lengths of the adjacent and the hypotenuse. Tangent(Tan) you apply Toa ; so you need to known the lengths of the opposite and the adjacent .
