1) Evaluate the following second derivative with respect to time, t (note that x is an unspecified function of time, i.e., x=x(t)). d dt [(ln x) (cos x) (3x + 2x)] 2) For following function, find the partial fraction expansion. 12x3 +10x2+5x+3 x4x3 + x + x 3) For T(s), determine phase and determine log of the magnitude when s = -2+3j (such that s is a complex number with a real part of -2 and an imaginary part of +3). T(s) = 3s+6 3s2 +18s + 108 1) Evaluate the following second derivative with respect to time, t (note that x is an unspecified function of time, i.e., x=x(t)). d dt [(ln x) (cos x) (3x + 2x)] 2) For following function, find the partial fraction expansion. 12x3 +10x2+5x+3 x4x3 + x + x 3) For T(s), determine phase and determine log of the magnitude when s = -2+3j (such that s is a complex number with a real part of -2 and an imaginary part of +3).
