Find the eq.n of the sides of a triangle having -LRB- 4,-1 -RRB- as a vertex , if the lines x-1 = 0and x-y-1 = 0are the equations of two int.bisectors of its angles ?
If roots of an equation x ^ n - 1 are 1 , a1 , a2 , a3 ... a n-1 then the value of -LRB- 1-a1 -RRB- -LRB- 1-a2 -RRB- -LRB- 1-a3 -RRB- -LRB- 1-an-1 -RRB- is ?
