Pl provide soln to the attached image!!
a n = Limit x 2 *(f(a n-1 /x) – f(0)) 2 , a n /a n-1 2 = Limit [ [ f(a n-1 /x) – f(0) ]/[ a n-1 /x – 0] ] 2 a n /x will be tendind to 0 as x tends to inf. hence RHS = f’(0) 2 So, an/an-1^2...

Sir Pls prove that the vector area of a triangle whose vertices are a vector bvector and cvector is 0.5(bvec cross cvector +cvector cross a vec+ a vector cross b vector) Thanks and Rgds, Jai
Let A be the endpoint of , B be the endpoint of vector , and C be the endpoint of vector . Then the vector from A to B is , and the vector from A to C is . So (1/2) | X | is the area of the ...
