Sine allows us to find out what a third side or an angle is using the equation sin(x) = opposite over hypotenuse (x being the angle).
Cosine has the same function but instead uses the equation cosine(x)= opposite over adjacent

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 the sine of 45 degress?
√ 1/2 = sine(45)= cosine(45) -Key
Are The sine and cosine of acute angles equal?
The sine and cosine of acute angles are equal only for 45° sin45° = cos 45° = 1/sqrt(2) = 0.7071
What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
Why are sine and cosine functions used to describe periodic?
because sine & cosine functions are periodic.
How do you find the max and min of sine cosine functions?
The maximum of the sine and cosine functions is +1, and the minimum is -1.
What are the trigonometric functions?
sine, cosine, tangent, cosecant, secant and cotangent.
What are circular functions?
Sine, Cosine, Tangent, Cotangent, secant and cosecant
What is difference of using sine to cosine and tangent?
They are different trigonometric functions!
What are functions in trigonometry?
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
Is it possible to model everyday sounds and speech with trigonometric functions like sine cosine tangent cosecant secant or cotangent?
Yes, but only sine or cosine will suffice.
What is period as it pertains to the graph of sine and cosine?
Period is how long it takes for the sine and cosine functions to restart repeating themselves. Both have a period of 2pi (360 degrees).
What are the six trigonometric functions?
Sine Cosine Tangent ArcSine ArcCosine ArcTangent
Why are sine and cosine functions called harmonic?
Sinusoid shape of the sine and cosine functions appear as oscillations. If an object is moving in a straight line and its position (function of time) can be described as sinusoid then it is referred to as a simple harmonic motion.
Advantages of sine and cosine functions?
Advantages of sine and cosine functions are in developing or creating plane analytic geometry. These functions are also beneficial in developing complex number plane, emphasizing scaling, rotation and reflection symmetries. which complement vertical and horizontal shifts.
