We find it by varying the current flowing through it and by measuring the deflection respectively and then we use the formula k=I/tan(theta)
reduction factor is used to find earth's magnetic field and compare galvanometer constants
You find the tangent to the curve at the point of interest and then find the slope of the tangent.
A tangent refers to the way in which a curve is measured. The amount of deviation from the segment line is measures, then a formula applied to find the tangent.
We can find it by using wheatstone bridge.
a tangent is a line that touches the circle at only ONE point

You need more than one tangent to find the equation of a parabola.
In order to find the equation of a tangent line you must take the derivative of the original equation and then find the points that it passes through.
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
1/(tangent of angle)
Take the inverse tangent -- tan-1(opposite side/adjacent side)
Use the four-step process to find the slope of the tangent line to the graph of the given function at any point.
