When you have a fraction on each side of the equals you can multiply the denominator of the left side times the numerator of the right. It will equal the product of the numerator on the left side times the denominator of the right.
That is called cross products.

Why we use sine angle in cross product while cos angle in dot product?
Because in dot product we take projection fashion and that is why we used cos and similar in cross product we used sin
What is the product of a numerator of one ratio and denominator of other ratio?
cross product
What is the product of numerators and opposite denominators in a proportion called?
The answer is cross products.
How do you find volume of a box with uniform cross section if only height is given?
You need to know the area of that cross-section. Once you have that number, the volume of the box is the product of (cross-section area) x (height).
What is the cross product of two vectors?
To find the cross product of two vectors:If a = [a1, a2, a3] and b = [b1, b2, b3], thena x b = [a2b3 - a3b2, a3b1 - a1b3, a1b2 - a2b1] or(a2b3 - a3b2)i + (a3b1 - a1b3)j + (a1b2 - a2b1)k
When you use cross product and dot product in vector?
Dot product and cross product are used in many cases in physics. Here are some examples:Work is sometimes defined as force times distance. However, if the force is not applied in the direction of the movement, the dot product should be used. Note that here - as well as in other cases where the dot product is used - the product is greatest when the angle is zero; also, the result is a scalar, not a vector.The cross product is used to define torque (distance from the axis of rotation, times force). In this case, the product is greatest when the two vectors are at right angles. Also - as in any cross product - the result is also a vector.Several interactions between electricity and magnetism are defined as cross products.
What is the cross product of a vector itself?
0 is a cross product of a vector itself
What are the applications of cross product and dot product in physics?
cross: torque dot: work
What is the geometrical meaning of cross product?
The cross product can be said to be a measure of the 'perpendicularity' of the vectors in the product. Please see the link.
Why you use cosine theta with cross product?
Normally you use sine theta with the cross product and cos theta with the vector product, so that the cross product of parallel vectors is zero while the dot product of vectors at right angles is zero.
Why the cross product of two vectors in plane is directed perpendicular to the plane?
because that is the def. of a cross-product!
Cross product is?
Cross product is a mathematics term when there is a binary operation on two vectors in three-dimensional space.
What happens to the cross products when the terms of a proportion are cross multiplied?
The cross product is created.
Why do all muscles cross a joint?
Why do all muscle cross a joint? Define the attachment points of muscle to bone?
in what components dot and cross product resolve?
A dot product is a scalar product so it is a single number with only one component. A cross product or vector product is a vector which has three components like the original vectors.
The product of numbers on the diagonal when comparing two ratios?
cross product.
Why we use sine angle in cross product while cos angle in dot product?
Because in dot product we take projection fashion and that is why we used cos and similar in cross product we used sin
