Question

Find the inclination θ (in radians AND degrees) of a line passing through the points:

(2,-2) (7,9)

Answer 1

slope=tan theta

Answer 2

slope=9--2/7-2=11/5

Answer 3

theta=tan inverse(11/5)

Answer 4

how would you convert 11/5 into degrees and radians?

Answer 5

65.55 degrees

Answer 6

yeah how do you convert it ?

Answer 7

finding the slope is easy. What I am not aware of as of yet is how the conversion process works.

Answer 8

i will tell how

Answer 9

@Krishnadas can you explain?

Answer 10

X radians=X degree*pi/180

Answer 11

X degrees=X radians*180/pi

Answer 12

like 30 degrees=30*pi/180=pi/6

Answer 13

got that??
