Multiply column XI by j sine of the angle in column IV andenter the result into column XIII.Example : For m = 2,j (0 - yil.5) sin 17.1 degrees = 3.4 + j?0.XIV. Total columns VIII, IX, XII, and XIII on each work sheet. (SeeTable I.)XV. Calculate the following quantities for each work sheet and expressthe result in polar form.Q = VIII + IX + XII + XIIIR = VIII - IX + XII - XIIIS = VIII + IX - XII - XIIIT = VIII - IX - XII + XIIIwhere VIII, IX, XII, and XIII are the totals obtained in step XIV.(See Table I.)XVI (5) . For each of the work sheets prepared for different assignedvalues of (£ — q> ), plot on the response graphs,Q = the upsweep response at
