Question

Find the slope of a line joining the points (sin 0, -cos) and (-sin 0,cos)​

Answer 1

Answer:

(sin°,-cos)        (-sin°,cos°)

x1      y1               x2,  y2

m=y2-y1=cos°-(-cos°)

   x2-x1    -sin°-sin°

= 2 cos°  = ( the number 2 and -2 will be cancelled)

  -2sin°

=sin 0  = cot°

  cos 0
