The angle between two vectors u1=x1i+y1j+z1k and u2=x2i+y2j+z2k can be determined by cos()=(x1*x2+y1*y2+z1*z2)/(|u1|*|u2|), were |u1|=sqrt(x1^2+y1^2+z1^1). Given...
The angle between two vectors u1=x1i+y1j+z1k and u2=x2i+y2j+z2k can be determined by cos()=(x1*x2+y1*y2+z1*z2)/(|u1|*|u2|), were |u1|=sqrt(x1^2+y1^2+z1^1). Given the vectors u1=3.2i-6.8j+9k and u2=-4i+2j+7k, determine the angle between them (in degrees) by writing one MATLAB command that uses element by element multiplication and the MATLAB built in functions acosd, sum, and sqrt. This is what I tried but i don't think it's correct because it should be one value and I got a vector u1=[3.2 -6.8 9] u2=[-4 2 7] theta=acosd(sum(u1.*u2)./sqrt(u1).*sqrt(u2)).
