If cos^(-1)(x)+cos^(-1)(y)+cos^(-1)(z)=pi(sec^(2)(u)+sec^(4)(v)+sec^(6)(w)) , where u, v, w are least non-negative angles such that u lt v lt w , then the value of x^(2000)+y^(2002)+z^(2004)+(36pi)/(u+v+w) is

If cos^(-1)(x)+cos^(-1)(y)+cos^(-1)(z)=pi(sec^2(u)+sec^4(v)+sec^6(w)) ,where u,v,v,w are least non-negative angles such that u < v < w then the value of x^(2000)+y^(2000)+z^(2004)+(36pi)/(u+v+w) is___

If cos^(-1)(x)+cos^(-1)(y)+cos^(-1)(z)=pi(sec^(2)(u)+sec^(4)(v)+sec^(6)(w)), whereu,v,u are least non-negative angles such that u

If w = u^(2)e ^(v) where u = x/y, v = y log x find (delw)/(delx)

If u=x+y+z,v=x^(2)+y^(2)+z^(2),w=yz+zx+xy then show that grad u , grad v and grad w are coplanar vector.
