Yes, trigonometric functions such as sine, cosine, and tangent can be applied to triangles other than right triangles through the use of the Law of Sines and the Law of Cosines. These laws relate the ratios of the sides of any triangle to the sines and cosines of their angles, allowing for the calculation of unknown sides and angles in non-right triangles. Thus, trigonometric functions are versatile tools applicable to various types of triangles.
you use the the 3 trigonometry functions , sin=opposite divided by hypotenuse cos=adjacent divided by hypotenuse tan=opposite divided by adjacent these are used to work out angles and side lengths in right angle triangles only!!! sine,cosine,tangent :)
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.
Tangent, in geometry, is used to describe when figures have only one point in common. In Trig. tangent is applied to triangles.
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
Sine and cosine functions are used in physics to describe periodic phenomena, such as simple harmonic motion, sound waves, and alternating currents in circuits. They help in modeling phenomena that exhibit oscillatory behavior over time or space. Sine and cosine functions are also used in vector analysis to analyze the components of vectors in different directions.
because sine & cosine functions are periodic.
to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A
"SOHCAHTOA" is a mnemonic device used to remember the trigonometric ratios of sine, cosine, and tangent in right-angled triangles. The acronym stands for Sine=Opposite/Hypotenuse, Cosine=Adjacent/Hypotenuse, and Tangent=Opposite/Adjacent.
sine and cosine
usually its used to find a missing angle or length of a right triangle. Of course there is more to trigonometry. any way you can use sine, cosine, and tangent, to fine the missing angle or length
If you mean 'sohcahtoa' then it is a memory aid for working out the properties of right angle triangles as follows:- Sine = opposite/hypotenuse Cosine = adjacent/hypotenuse Tangent = opposite/adjacent
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.

You usually need all three primary functions. The sine and cosine functions are used to resolve the vector along orthogonal axes, and the tangent function is used to find its direction.
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
