MATLAB: How to find angle made by tangent at the end of a curve

differential equationsgraphintegrationnumerical integrationplotplotting

Hi,

I have attached the image of a curve obtained by using ode45 . Now my intention is to find the angle that the tangent at final points of the free end of the curve makes with the x-axis.

How do I do it?

Thank you

Get the equation of tangent.....convert it to y = mx+c form......m should gives you slope which is the angle you want.

MATLAB: Finding the angle of inclination from two end points of a line.

point1 = [22, -114];
point2 = [693, -233];
x1 = point1(1);
y1 = point1(2);
x2 = point2(1);
y2 = point2(2);
slope = (y2 - y1) ./ (x2 - x1)
angle = atand(slope)

If s1 is the derivative of the curve on the left at the middle point and s2 the derivative of the curve on the right side at the middle point, the upper angle between the two tangent lines to the curves at that point is given in radians by:

 a  =  mod(atan2(s2-s1,-1-s1*s2),2*pi);

To convert the angle to degrees, multiply this by 180/pi.
