For school trigonometry, it is used to find the angles of a triangle when only the lengths of the sides are known.
Later on, in mechanics, you may come across the decomposition of forces along and across the line of motion. In calculus you may come across it in second order differential equations.
What else can I help you with?
Which trigonometric functions are even?
Cosine and secant are even trig functions.
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.
How do you use cosine?
cosine = adjacent/hypotenuse. It can be used as other trig functions can.
What is the use of orthogonality in fourier series?
Orthogonality in Fourier series is used to simplify the representation of periodic functions as sums of sine and cosine functions. Because the sine and cosine functions are orthogonal over a defined interval, the coefficients for each term can be calculated independently. This property allows for the efficient decomposition of complex signals into simpler, non-overlapping components, making it easier to analyze and reconstruct signals in various applications, such as signal processing and communications.
What is difference of using sine to cosine and tangent?
They are different trigonometric functions!
Which trigonometric functions are even?
Cosine and secant are even trig functions.
Why are sine and cosine functions used to describe periodic?
because sine & cosine functions are periodic.

What does cosine mean on a calculator?
The same thing that cosine means in trigonometry, a calculator just allows you to calculate such functions quickly.
What are functions in trigonometry?
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
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 cos 66.5 degrees?
The cosine of 66.5 degrees is approximately 0.4067. This value can be found using a scientific calculator or trigonometric tables. Cosine functions are used to determine the adjacent side of a right triangle relative to the hypotenuse. In practical applications, this value is often used in various fields such as physics, engineering, and computer graphics.
