What else can I help you with?
Do you need a right traingle to use sine cosine and tangent?
Yes, sine, cosine, tangent definitions are based on right triangles
What jobs use sine cosine and tangent?
Trigonometry
How do you know when to use tangent cosine or sine?
It depends on what information you already have. For example, if you know the length of two sides of a triangle, you can easily find the tangent. Or, if you know the length of two angles and a side, you can find the other sides as well, using the tangent, cosine, and sine as needed.
How do you figure the base of a triangle when you know the dimension of the other two sides?
If it is a right triangle, you can use the Pythagorean Theorem. If you know the angle measures, you can use cosine/sine/tangent.
When to use sin and cos.?
The sine and cosine were originally developed for use in surveying. They provided a way to measure the distance across lakes and around mountains. Soon they were found to be useful in navigation. The sine was used to calculate pi. When electrical measurements were made, the sine law was used. If you want to know when to use the sine and when to use the cosine, you will need to get a trig book, a physics book, an astronomy book, a sailing book, and a few other books and read them all.

Where to use sine and cosine in physics?
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.
How do you know whether to use sin or cosine?
To determine whether to use sine or cosine, consider the context of the problem and the definitions of each function. Sine is used when you need the ratio of the opposite side to the hypotenuse in a right triangle, while cosine is used for the ratio of the adjacent side to the hypotenuse. Additionally, in unit circle problems, sine relates to the y-coordinate and cosine to the x-coordinate of a point on the circle. Identifying whether you are working with angles or sides will help guide your choice.
How do you find the length of a side in a triangle that is not a right triangle?
Use either the Sine or Cosine rules depending on the information you know about the triangle.
How do you figure the base of a triangle when you know the dimension of the other two sides?
If it is a right triangle, you can use the Pythagorean Theorem. If you know the angle measures, you can use cosine/sine/tangent.

When should we use either the sine or cosine function in statics analysis?
In statics analysis, we use the sine function when dealing with forces that are perpendicular to a reference axis, and the cosine function when dealing with forces that are parallel to the reference axis.
Does acoustics use trigonometry?
Yes, because all sound waves can be modelled as sine (or cosine) waves, or combinations of sine waves.
How do you find theta for right triangle?
You can use your trigonometric functions (sine, cosine, and tangent).
How do you solve for a triangle with two angles but no lengths?
you can use the sine, cosine, tangent formula.
