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 :)
Tangent, in geometry, is used to describe when figures have only one point in common. In Trig. tangent is applied to triangles.
Various trigonometric functions, such as sine or cosine, show the relationship between the lengths of sides of a triangle and the angles between those sides. So trigonometry is used to calculate angles, lengths and distances using right triangles. Right triangles are those that have one angle of exactly 90 degrees. Example: You want to find the height of a tree. Measure off a fixed distance from the tree and measure the angle between the ground and the line-of-sight to the top of the tree. The height of the tree = the distance to the tree times the tangent of the angle between the tree and the ground, ie tan(x).
Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
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.
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
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

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.
A way to remember the definitions of the three most common trigonometry functions: sin, cos and tan. Used as a memory aid for the definitions of the three common trigonometry functions sine, cosine and tangent.
The inverse (negatives) of sine, cosine, and tangent are used to calculate the angle theta (or whatever you choose to name it). Initially it is taught that opposite over hypotenuse is equal to the sine of theta sin(theta) = opposite/hypotenuse So it can be said that theta = sin-1 (opp/hyp) This works the same way with cosine and tangent In short the inverse is simply what you use when you move the sin, cos, or tan to the other side of the equation generally to find the angle
not only sine, even cosine can be used to represent waveforms. the other trigonometric ratios cannot be used ,as at some points, their numerical value rises to infinity which is impossible for any normal wave with finite energy and amplitude. for example, tangent at any odd no. multiples of 900 becomes infinity. so do all the other trigonometric ratios. only sine and cosine are bounded functions whose values lie between -1 and 1 for any angle this is similar to the behavior of any ordinary wave. so, they are used.
