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.

How do you find theta for right triangle?
You can use your trigonometric functions (sine, cosine, and tangent).
How do you find the cosine and the sine?
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
What is Sin cosine and tangent?
Sin, cosine, and tangent are considered the three main of trigonometry, commonly written as sin, cos, and tan. sin(θ) = O/H cos(θ) = A/H tan(θ) = O/A Where O is opposite Where H is Hypotenuse Where A is Adjacent To assist further in understanding: http://www.mathsisfun.com/sine-cosine-tangent.html
Why is it tangent 90 degrees is undefined?
Because it tends to infinity. Additionally, tangent can be expressed as sin theta divided by cos theta. The sine of 90 is 1. The cosine of 90 is 0. That would be 1 divided by 0, or division by zero; which is undefined.
What is the sine of 45 degress?
√ 1/2 = sine(45)= cosine(45) -Key
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
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 find sine cosine and tangent of 210 degrees?
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
Where to use sine and cosine in physics?
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
How do you know when to use sine over cosine or cosine over sine?
You can choose either or but tangent which is sin/cos seems to be the most common way.
What is the relationship between the tan and cot?
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
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.
The laws of sine cosine and tangent are used where?
in trigonometry
Does tangent of x equal cosine divided by sine?
No, it does not.
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.
