Solve for t, 0 < t <2pi 20sin(t)cos(t)=-8sin(t) t= ? Solve Csc(2x)-2=0 for the four smallest positive solutions x= Solve 2Cos^2(x)+2cos(x)+1=0 for all solutions 0<x <2pi x= Solve 2sin^2(x)-5sin(x)+2=0 for all solutions 0 <x <2pi x=? Solve sin^2(w)=-5cos(w) for all solutions 0 < w < 2pi w= ? if you could go over the steps of at lease one that would really help me understand and pull apart what I am supposed to do to solve more of these.
Pl. For the circuit shown, given that: vsi (t) 10 cos(100t +/3) V, vs2 (t) -2cos(300t -/2) V, R1-22 L 0.2 H, Detremine the current i and the voltage vc Hint: To solve this problem we must use superposition. We first have to solve it in three separated circuits (in no particular order): DC steady state (supress all sources but the DC supply vs3). Phasor solution of circuit with vs1 and supression of the remaining sources, Phasor solution of circuit...
