The dot-product and cross-product are used in high order physics and math when dealing with matrices or, for example, the properties of an electron (spin, orbit, etc.).
ughhhi need info too
Measuring a lawn Calculating the speed of a falling object
Most houses are built with walls parallel to each other.
Signed numbers are used for:TemperatureMoney, Accounting, or EconomyMath Problems
real life situations where in rational algebraic equation is applied/used
Because in dot product we take projection fashion and that is why we used cos and similar in cross product we used sin
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.
Proportions are used in real life to determine prices of things.
Believe it or not, school is a real life situation. If you are using it in school it real life for you.
If you are in school and are studying trig then you are using trig in real life.
It depends on the type of product used. A dot or scalar product of two vectors will result in a scalar. A cross or vector product of two vectors will result in a vector.
People use line graphs in businesses, and to compare data. Line graphs are mostly used when people are entrepreneurs. They figure out profit this way. Line graphs are also used when a product is made. They decide if they should continue to make this product, by how well the product sells. Line graphs show the change.
Thus, informational advertising is used early in the product life cycle.
Real useing you house.
They are not.
Yes, they are used.
they are not trust me
