Application of Tangents and Normal in Real Life

Tangent

A tangent is a horizontal line on a curve that touches the point on the curve and the slope of the curve is the same as the gradient/derivative. One may derive how to obtain the tangent’s equation at whatever point out from the definition. The tangent’s equation to curve at x = x0, given a function y = f(x). 

Normal

Straight-line which intersects the curve at a point and which is perpendicular to a tangent at a point is called Normal. If the slope is written by n & slope of its tangent at a point or the gradient’s value at a point is denoted by m; therefore we obtain m × n = -1

The Centrifugal force, the centripetal force, and the angular momentum are all experienced by an object moving in a circular path. The item is flung outward by centrifugal force. It wants to leave toward the centre due to the centripetal force. The item travels inside a circle because the two forces are balanced. It wants to travel in a straight path due to angular momentum. This energy would cause the item to proceed at such a tangent towards the circle if either of the two forces were to vanish. So, what happens if a swing ride is no longer available? Each would veer off in a different direction from the circle. Because each person’s seating placement determined his or her unique tangent, they’d each soar in various directions until gravity dragged them down to the surface.

Tangents used in Daily Life

Tangents are used by NASA to determine how and where to conduct space missions. A spacecraft must move quickly enough to avoid the gravitational attraction of Earth. NASA must know how and when the spacecraft will be launched in order for it to go in the right direction after it exits the orbit. The scientists of NASA are so skilled at estimating tangents that the scientists can launch a spacecraft from Earth and as well as predict where this will fall after seven months onto Mars. 

Secant

The secant is the line that connects two points on a circle. The term secant derives from a Latin word is secure, which meaning “to cut”. It’s also known as the expansion of the circle’s chord which extends beyond the circle. A secant may be found in many locations in everyday life, especially if the circles or the curves are present. For example, as in construction constructing curving bridges and determining the length between the circling moon and various sites on the Earth. Secants have a variety of fascinating features that aid in the development of enigmatic geometric structures. There are several circle theorems depending on the circle’s secants and the intersecting secants. When at the exterior points, the two secants cross each other, the combination of one entire secant length as well as its external length equals the combination of all the other entire secant length and also its external length, according to the crossing secants theorem. This secant theorem can sometimes be known as the tangent power theorem.

Conclusion

Tangents and normal are two lines that are connected to curves. The tangent, or a path that intersects the circle at a certain point, exists for each point in the curve. A normal line lies perpendicular towards the tangent just at the touch point. The tangent to such a curve is indeed a horizontal line that intersects the curve till a certain place. It doesn’t cross the curve, and only touches the specific spot that has previously been specified. A normal horizontal line is perpendicular to such a tangent.
