Statement  :                                                                                                       Back 

              If { un } is a sequence of positive terms such that

(a)    Un ≥ un+1 ∀ n

(b)    Lim un =0 then the alternating series Σ (-1)n-1 is convergent.

sin30=1/2 what it means? 🤔 #sin30, #trigonometry

   we know sin30= 1/2. what it means ?   🤔        In a right triangle if the sine of  angle  30  = 1/2   means that the length of hypotenuse is always double the length of opposite side. i.e. if we take 6cm as length of opposite side then length of hypotenuse is 12 cm if we take 100 cm as length of opposite side then the length of hypotenuse is 200 cm etc.                      If any one has any doubts in trigonometry or any mathematic concern topics please ask in the comment section .Also anybody of you want to give me friendly suggestions  post in the comment section. * what is dimension of an object? * 4th dimensional object Hypercube . * what is angle?   Page navigation #sin30 #= #1/2 #what #it #means #?  #maths #mathematics # trigonometry  People also search for Iit mathematics  books IIT Mathematics  Questions Iit mathematics  ...

REAL ANALYSIS- INTRODUCTION #real #analysis #introduction

  REAL ANALYSIS- INTRODUCTION :                                                                  Real Analysis is a fundamental branch of mathematics that it rigorously studies real numbers, sequences, series, limits, continuity, differentiation and integration. It provides a formal frame work for understanding calculus, ensuring that intuitive concepts like limits and continuity are precisely defined and logically sound.                                             At its core , real analysis answers fundamental questions such as   * What does it mean for a sequence to converge?  * how do we rigorously define continuity and differentiability?  * What properties make functions well...
