Suppose you have a straight line that goes through the origin and makes a 30 degree angle with the positive x-axis. What would the equation of this line be? Explain how you could use one of the six trigonometric functions to help you write the equation of this line.

Question

anonymous · Answer

the slope of the is tan 30 degrees which is 1/sqrt3
the line goes through (0,0)
using the standard equation of the line y = mx + c
-  the equation of the line is:

y = (1/sqrt3) x + 0
ie
y = x/sqrt3
