Use the rule where m is the gradient of the line
This is a simple question, but for some reason I still can't get it.
Find the equation of a straight line which asses through the point (2,3) and is inclined at 30 degrees to the positive direction of the x-axis.
How do I solve it? Also I think you need to find the gradient from the 30 degrees but how do you do that? (with and without a scientific calc)
When they say "Positive direction of the x-axis, what do they mean by that).
Thanks in advance
Don't mean to ask but I just typed in tan(30) into my graphics calculator and I got root 3 divided by 3? How did they get this, I think thats why my question is wrong because I got 0.57.
EDIT - Nevermind, just drew up a triangle. I will post my answer in a second
EDIT 2 - I got m to equal 1 divided by root 3, do I need to rationalize it? I think thats where I stuffed up, coz I wasn't supposed to rationalize it?
