Studied? Yes!

 The Tangent and Secant. Circle and Trigonometry . One is related to a closed figure with the highest number of sides ( basically infinite sides ) and the other is about a closed figure with the least number of sides . At first glance, we don't see any correlation between these two concepts, but they have the same terms expressing their important topics.  Most people might think that the mathematicians of that time just ran out of words to name the innumerable things they discover but that is not the case in this situation.  The Tangent and Secant of a circle and that from trignometry have a cardinal relation, which we will dig deep and uncover in this blog,  Let's consider a circle with centre O and radius 1 cm ( for making calculations easier) .Hence OA and OB are radii of the circle ( Both of 1 cm). Next, draw a line segment perpendicular from B to OA and name this point C. Hence BC is perpendicular to OA. Now, OBC is a right angled triangle. Considering the trigonometric fu

Electricity and Magnetism, Two seemingly different topics ( atleast till grade 9) are actually just two different faces of a coin, one is related to the other, one instigates the other.  Taught to high schoolers in vast detail, it carries as much importance in our report cards as it does in our real life ( Now, imagine living your life without TV or your laptop , these devices use both magnetism and electricity! That is the percentage of  importance it plays in our report cards too ( *gulp*)) Hence, in this blog we will go through the important formulas, units and concepts in these chapters  So, let's start!    Important units and formulas 1) Electric charge -- Coloumb                               -- CGS Unit - Electrostatic unit (esu) ( 1 Coloumb = 3 * 10⁹ esu)                               -- Faraday ( 1F = 96500C)                              -- Ampere - hour ( 1 A-hr = 3600 C) 2) Electric filed intensity - The force acting on a unit positive charge, place at a point within t
