Question

Find the slope of line joining the point (0,sintita ) and( costita ,0)

Answer 1

Answer:

$- \tan(theta)$

Step-by-step explanation:

$slope = \frac{y2 - y1}{x2 - x1}$

$given \: : \: x1 = 0 : y1 = \sin(theta) \\ x2 = \cos(theta) :y2 = 0$

$slope = \frac{ 0 - \sin(theta) }{ \cos(theta) - 0 }$

$= \frac{ - \sin(theta) }{ \cos(theta) }$

$= - \tan(theta)$
