Unit circle and point P on circumference whose coordinates x and y represent cosine and sine of the highlighted angle, respectively After this relevant digression on the definition of the trigonometric functions, let's show thetrigonometric graphs, that is, the graphs of the referred functions. ...
The unit circle can be used to understand the values of sine, cosine and the tangent ratios. The horizontal line is the cosine function, while the vertical line is the sine function. A perpendicular line drawn at the end of the circle will represent the tangent function. There are several ...
I see it like this: we have a starting angle, $x$. We increase it a smidge ($dx$), which we can placealongour unit circle (since radians aredistance traveledalong the perimeter). We then draw a mini-triangle based on $dx$, similar to the large one, which shows the height and wi...
Or, if you prefer, in radians:Examples:sin(0.1π) = cos(0.4π) tan(π/4) = cot(π/4) sec(π/3) = csc(π/6)Double Bonus: The Pythagorean IdentitiesThe Unit Circle shows us thatsin2 x + cos2 x = 1The magic hexagon can help us remember that, too, by going clockwise around ...

x.Notice that the triangle is inscribed in a circle of radius 1. Such a circle, with a center at the origin and a radius of 1, is known as a unit circle. Figure 1. We can define the trigonometric functions in terms an angle t and the lengths of the sides of the triangle. The ...
Most programmers think in terms of degrees, with 360 forming a circle. The radian is a more natural unit of measurement for angles. Radians are based on pi, the number that relates diameter to circumference and ties all of trigonometry together. ...
