If `sinx+cosecx =2` then `sin^nx+cosec^nx=`

If sin+cosecx = 2, then sin^(n)x +cosec^(n) x is equal to

If sinx+cosecx=2 then sinx=

If cosx+secx=2," then "cos^nx+sec^nx is equal to

If sinx+cosecx=2 , then, for all n in N , the value of: sin^nx+cosec^nx= (a) 2 (b) 2^n (c) 2^(n-1) (d) 2^(n-2)

cos mx = sin nx

If sin+"cosecx"=2 , then what is the value of sin^(4)x+"cosec"^(4)x ?

If cosx+secx=-2 then for a positive integer n, cos^nx+sin^nx is

If cosx+secx=-2 then for a positive integer n, cos^nx+sin^nx is

If A=((cosx,sinx),(-sinx,cosx)) then prove that A^n=((cosnx,sin nx),(-sin nx,cosnx) for all positive integers n.
