Vector product of two space vectors
Vector AB=(x1, y1, z1), Vector CD=(x2, y2, z2)
Vector AB×vector CD=(y1z2-z1y2, x2z1-x1z2, x1y2-y1x2)
A new vector is generated whose direction is perpendicular to the plane defined by vector AB, vector CD and whose direction is defined by the right-hand rule.
Modulus Calculation of Product of Two Vectors If a vector =(2,3) b =(4,5), then |a vector ×b vector | how to calculate? Calculation of the product of two vectors If a vector =(2,3) b =(4,5), then |a vector ×b vector | how to calculate?
A*b=2*4+3*5=23
So |a*b|=|23|=23
The length of vector a plus the length of vector b A. is equal to the length of vector a+b B. is greater than the length of vector a+b C. Length less than vector a+b D. Length greater than or equal to vector a+b
When the angle between vector a and vector b =180°, AB + BC = AC
When the angle between vector a and vector b =180°, AB+BC > AC (the sum of two sides of the triangle is greater than the third side)
If the length of vector a and vector b is equal to 4 and 3, respectively, and the included angle is 60 degrees, then what is the value of |a+b|?
| A |=4
|B |=3
Included angle is 60 degrees
A*b=|a*|b|*cos=12*(1/2)=6
So
|A+b|=√[|a|2+2ab+|b|2]=√[16+12+9]=√37
