What are the six trigonometric functions of an angle?

1 Answer

Oct 31, 2015

$sin (x)$ $sin(x)$ , $cos (x)$ $cos(x)$ , $tan (x)$ $tan(x)$ , $csc (x)$ $csc(x)$ , $sec (x)$ $sec(x)$ , $cot (x)$ $cot(x)$ .

Explanation:

$cos (x) = sin (\frac{π}{2} - x)$ $cos(x)=sin(pi/2-x)$

$tan (x) = \frac{sin (x)}{cos (x)}$ $tan(x)=frac{sin(x)}{cos(x)}$

$csc (x) = \frac{1}{sin (x)}$ $csc(x)=1/sin(x)$

$sec (x) = \frac{1}{cos (x)}$ $sec(x)=1/cos(x)$

$cot (x) = \frac{1}{tan (x)}$ $cot(x)=1/tan(x)$
