Linear speed is how fast the arc of any given angle is growing. This is useful to determine the linear speed with the relationship to time. »

To find any given theta angle you will need to know the arc length and the radius. Any given angle gives the rise to the arc, »

Angular speed is how fast the central angle changes in respect to time. Below you will see an angle that is changing by $\theta$ distance. With »

Two acute angles that equal to the sum of 90 degrees are complementary angles. $$\alpha =90°-\beta$$ »

A ray is created based on an initial point and expanded out to n length. »

Acute Angle $$cos(x)>0\Rightarrow 0°< x < 90°$$ Obtuse Angle $$cos(x)<0\Rightarrow 90°< x <180°$$ »

Here is a list of degrees to radians conversions that you need to have memorized. You need to be able to recite each one of this »

The function tan(x) $$tan(x)=\frac { opposite }{ adjacent }$$ The inverse of the function $$tan(x)=\frac { adjacent }{ opposite }$$ Or you can also represent tan(x) »

The function cos(x) $$cos(x)=\frac { adjacent }{ hypotenuse }$$ The inverse of the function $$sec(x)=\frac { hypotenuse }{ adjacent }$$ »

The follow triangle shows the relationships between $x$ and the relating sides. Soh $$sin(x)=\frac { opposite }{ hypotenuse }$$ Cah $$cos(x)=\frac { adjacent }{ hypotenuse }$$ Toa $$tan( »

To convert degrees to radians you will need to multiply degrees by pi and divide by 180. $$f(x)=\frac { \pi (x) }{ 180 } $$ »

To convert radians to degrees you will need to multiply the radians by 180 and divide by pi. $$ f(x)=\frac { 180(x) }{ \pi } $$ »

$$1°=\frac { 1 }{ 360 }$$ »

$$ y-{ y }{ 1 }=m(x-{ x }{ 1 }) $$ »

A radian is a unit measurement of an angle. $$2\pi = 360°$$ $$\pi = 180°$$ $$1radian=(\frac { 180 }{ \pi } )\approx 57.3°$$ »

An angle is composed of three different parts. Vertex Terminal Initial Side »
