Maths: The Straight Line Watch
Is there anyone who can help with this particular maths question?
Finding the gradient of a line given only an angle?
An explanation is much appreciated
tan(30) should be well known as a surd.
NB be careful about the sign.
Thank you, so I have put tan(30) into my calculator but do I just change the sign because it’s a negative sloping line?
The sign is important. Really it would be tan(-30) or tan(150) measured wrt to the positive x-axis.
