If you know the measure of one angle, and the length of one side of a triangle, you can find the measures of the other sides and angles. From there, you can find the values of the other trig functions.
cos (x) = sin (90-x) in degrees
there are other identities such as cos^2+sin^2=1, so cos^2=1-sin^2
What else can I help you with?
What are circular functions?
Sine, Cosine, Tangent, Cotangent, secant and cosecant
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.
What is trigonometry's circular function?
The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.
What are the six trigonometric functions of special angles?
sine, cosine, tangent, cosecant, secant and cotangent.
How are sine and cosine and secant related?
Sine and cosine are cofunctions, which means that their angles are complementary. Consequently, sin (90° - x) = cos x. Secant is the reciprocal of cosine so that sec x = 1/(cos x). Knowing these properties of trigonometric functions, among others, will really help you in other advance math courses.
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 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 is the Fourier transform of a sine wave?
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
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.
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.
