A line passing through the point (3,0)makes an angle with 30degree with +ve direction of x-axis.
If this line is rotated through an angle of 15degree in clockwise direction , find its equation in new position.
First of all we have to find the slope of the line
slope(m) = tan of the angle
⇒ tan 30 = 1/√3
The point where the line passes through is().
In this case,
The equation for the equation of a line is:
Now,
When the line is rotated through an angle of 15degree in clockwise direction
The new angle =
slope(m) = tan of the angle
The equation for the equation of a line is:
