,
Q) Find the slope of the line which makes an angle of 60 degrees with the positive direction of Y - Axis.
My answer is: negative sqrt of 3 The text book answer is: negative 1/sqrt of 3
What might be the reason?
It makes an angle of 30 degrees with the negative x-axis, that is, an angle of $\displaystyle \theta = 150^0$ with the positive x-axis. And $\displaystyle m = \tan \theta$ ....
