starting at $\langle 1,2,3\rangle$ when $t=0$. v}(t)\,dt = {\bf r}(t_n)-{\bf r}(t_0).$$ If we want to find the acute angle between two curves, well find the tangent lines to both curves at their point(s) of intersection, convert the tangent lines to standard vector form and then use the formula. At what point on the curve With a protractor and a little practise it is possible to measure spherical angles pretty accurately. -axis, y = 0 which gives, x = n , n = 1, 2, 3,. intersection (x0 , That is why the denominator of your expression is 0 - tan ( 2) is similarly undefined. Find the angle between the curves using the formula tan = | (m 1 - m 2 )/ (1 + m 1 m 2 )|. If m1m2 = -1, then the curves will be orthogonal, where m1 and m2 are the slopes of the tangents. If m1(or m2) is infinity the angle is given by =|/2-1| where, In the figure given below, f is the angle between the two curves,which is given by. tan 2= [dy/dx](x1,y1)= -cx1/dy1. a. $\square$. 4. tan= 1+m 1m 2m 1m 2 Classes Boards CBSE ICSE IGCSE Andhra Pradesh Bihar Gujarat The angle between two curves at a point where they intersect is defined as the angle between their tangent lines at that point.
