The dot product of a vector is different than multiplication in that you are multiplying two vectors together. If you had a vector A<1, 2> and a vector B<2, 4>, the dot product A·B would be equal to <Ax*Bx, Ay*By> or <2, 8>. Reflection. As mentioned above, ...
Dealing with the trigonometric functions of two angles may be pretty tough, unless you know the relationship between them. So what happens if you know that α and β are supplementary angles? Then, as α + β = 90° (π/2) we can state that: The sine of an angle equals the cosine ...
The term x'iXj=cos 0ij estimates cos 0ij= iy. The asymptotic joint distribution of the terms will be studied when all the vectors i are distinct, and for the special case when all the vectors i=, so that all the terms are zero. These very different results have a variety of ...
Find the values of 'a' which the vector →r=(a2−4)ˆi+2ˆj−(a2−9)ˆk makes acute angle with the coordinate axes. View Solution Write the the projections of →r=3ˆi−4ˆj+12ˆk on the coordinate axes. View Solution Find the angle between the vectors →a=ˆ...
Vectors parallel to the tangent lines are 1, (√ 2)2 and 1,- (√ 2)2, and the angle θ between them is given by(split)cos θ &= (1,(√ 2)/2⋅ 1,(-√ 2)/2)( 1,(√ 2)/2 1,(-√ 2)/2 )&= (1- 1/2)(√ ( 3/2)√ ( 3/2))&= (1/2)(3/2)&= 13(...
This involves the study of manifolds that are equipped with the additional structure of a Riemannian metric, a rule for measuring curve lengths and angles between tangent vectors. A Riemannian manifold has curvature, and it is specifically this curvature that makes up the laws of classical Euclidean...

A straight angle is an angle between two rays with a measurement of 180°—this would look like a straight line. AngleDegrees Acute <90° Right 90° Obtuse >90° and <180° What is an Acute Angle? Acute angles are the smallest type of angle, and they are defined as being less than...
To prove the theorem, one other relationship between angles created by the lines must be accepted as a postulate. In this form of the proof the interior angles are treated as consecutive angles of a parallelogram since the lines are parallel. The corresponding angles a c are equal. In this ...
