There are two ways to express the tangent plane equation. Given that it is the sum of the two distinct tangent vectors, its parametric equation is r=r0+sru+trv.

A surface in Euclidean space is considered to be parametric if it can be described by a parametric equation with two variables. Parametric representation is another reasonably general technique for describing a surface in addition to implicit representation.

On the other hand, tangent planes to a surface are planes that are "parallel" to the surface at the point where they barely touch it.

A solar eclipse when the moon is at its far end of orbit, leaving a ring of light around the black circle of the moon is called a ring of fire.

When the moon passes in front of the sun and casts a shadow on Earth, there is a solar eclipse. Only during the new moon phase, when the moon travels squarely between the sun and Earth and casts shadows on its surface, can a solar eclipse occur.

The North and South Poles are unable to view total solar eclipses. Solar eclipses that are nearly identical occur every 18 years and 11 months.

Answer: Equivalence Point

Explanation:

An Acid-Base Titration is a titration carried out to determine the strength or concentration of an acid or a base by neutralizing it with a standard solution of an acid/base of known concentration.

At equivalence point in an acid-base titration the moles of base become equal to the moles of acid. This implies that , at this point of the titration the amount of titrant (standard solution of acid/base) added is just enough to neutralize the analyte (acid/base whose strength has to be determined).

The progress of these reactions are kept track of by pH indicators like phenolphthalein or methyl red.

The total resistance of a Parallel circuit with three resistors will be one third times lesser than the resistance of the circuit with single resistor.

A resistor is a passive two-terminal electrical component used in circuits to implement electrical resistance. Resistors have a variety of purposes in electronic circuits, including lowering current flow, adjusting signal levels, dividing voltages, biassing active components, and terminating transmission lines.

High-power resistors that can generate many watts of heat instead of electrical energy can be utilized as test loads for generators, power distribution systems, and motor controls. With temperature, time, or operating voltage changes, fixed resistors’ resistances only slightly fluctuate.

Variable resistors can be utilized as force sensors, heat sensors, light sensors, volume controls, lamp dimmers, humidity sensors, and chemical activity sensors.

When two or more resistances are connected between two points and each has a different current direction, the resistances are said to be connected in parallel.

In such circuits, the branches intersect at a common location, causing the current to branch out and then recombine.

When two or more resistances are connected end to end and the same current passes sequentially through all of them, this is referred to as a series connection. The total resistance in this situation is equal to the entire number of Individual resistances included in the series combination.
