(a) Find the differential dy. y = COS(xX) dy = (b) Evaluate dy for the given values of x and dx. (Round your answer to three decimal places.) X = W H dx = 0.01. dy =Find the differential of the function. = D 3 sin (90) OV =The resistance in a (ertain wire is R = 500 + O'OSDTZ. If Ti; measured to be SDJDF with a possible error of :BDF, use differentials to find the approximate maximum error (in m and percentage error in R. (Round your answers to two decimal places.) maximum error 0 percentage error \"A
