well, I am lost...im not sure if this goes in college or k-12, but I am in grade 12 in Canada...and I am learning here, so i guess I am at the right place,
any wyas...i need help, with parametric and vector eqns of lines, since I am failing this course horribly...my teacher sucks and marks hard and I don't get anything!...
so now for the questions
The angle ø, 0° < ø < 180°, That a line makes with the positive x-axis is called the angle of inclination of hte line.
A) find the angel of inclination of each of hte following lines.
_
i) r = (2,-6) + t(3,-4) ii) r = (6,1) + t(5,1)
B) prove that the tange of the angle of inclination is equal to the slope of hte line.
