    Engineering Dc motor

    Homework Statement the speed of dc motor is given by N=60(A/p)(V-Ia*Ra)/(Z*phi) where, A=no. of parellel paths P=no of poles V=voltage applied at dc motor Ia= armature current Ra=armeture resistence Z= total no. of armature conductor phi=flux per conductor. but if some how we stop...

    Limit of multivariable function

    Homework Statement lim(x,y)->(4,pi)(x^2sin(x/y)), i tried it by polar as well as epsilon delta method, but by polar coordinate method it is coming that " limit doesn't exits" but by epsilon delta method "it exists & is equal to (epsilon+(16/(2)^(1/2)) )^(1/2)-4. Homework...
