If sinx+cosecx =-2 , then valueof Sinnx+cosnx is (n belongs to N)
Ans is -2n plzz explain..
Hey I dont think the answer is possible
simple example let n = 2 then sin2x + cos2x which is always equal to one
How come the answer is -2n because then it will become 22= -4 WRONG
Also for first condition sinx comes to be equal to -1 then cosx = 0 cosecx =-1 and similarly other t ratios
I think the question might be sinnx+cosecnx = -1n+ -1n = 2x(-1)n
