If `sinx+siny+sinz+sinw=-4" then the value of "sin^400x+sin^300y+sin^200z+sin^100w` isA. `sin^400x.sin^300y.sin^200z.sin^100w`B. `sinx.siny.sinz.sinw`C. 4D. 3

Answer» Correct Answer - C
`sinx+siny+sinz+sinw=-4`
`rArrsinx=siny=sinz=sinw`
So,`sin^400x+sin^300y+sin^200x+sin^100w`
`=-(-1)^400+(-1)^300+(-1)^200+(-)^100=4`
