 Problem :

Show that the set { ( 1 , 2 , 1 ) , ( 2 , 1 , 0 ) , ( 1 , -1 , 2 } forms a basis of V3 ( F ).

Solution :


 * Theorem on Linear Dependence 

* linear sum of subspaces

* What is a vector space

* linear span of a set 

  * L ( S ) = L ( S' )

 * Theorem on vector space  

 * Historical Introduction to Linear Algebra

 * Let V(F) be a vector space and let W ⊆ V. The necessary and sufficient conditions for W 

            to be a subspace of V are (i) 𝜶 𝞊 W, 𝞫 𝞊 W ⇒  𝜶 - 𝞫 𝞊 W

                                                     (ii) a 𝞊 F , 𝜶 𝞊 W ⇒ a𝜶 𝞊 W.

* Let V(F) be a vector space and let W ⊆ V. The necessary and sufficient conditions for W 

    to be a subspace of V is  𝜶 𝞊 W, 𝞫 𝞊 W ⇒  a𝜶 +b𝞫 𝞊 W

 * Problem 1 on subspace of a vector space 

* Problem 2 on subspace of a vector space

 * Intersection of subspaces is again a subspace

  * union of subspaces of a vector space

  * Problems on linear combination

 * Pairwise sums of Linearly Independent Vectors

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

For a video explanation, click the link 👉  https://youtu.be/kXOzH8k_klw      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 ". For Example ,  Suppose lenth of opposite side = 6 cm   then      lenth of its hypotenuse = 12 cm ***       Note :   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  #iit #jee #mains #eamcet #iit-jee #iitjee maths  #trigono...
