Problem 4 (P-2.9 a, b) [10] x(t) = 2 sin(w。t + 45°) + cos(wt) a) Express x(t) in the form x(t) = A cos(w¸t + ¢) [5]. b) Assume @=5π rad/s. Plot x(t) between -1≤ t≤2 using Matlab/Octave [5].

By adopting COSINE as the base function for phasors, what part of the Euler's identity is used? (A cannot be determined B none of the choices C real D imaginary E) either one is acceptable

(p) Suppose for some arbitrary system: 2 H(s) = 1 20.97 12- 0.97 s+2 - j2 s+2 + j2 Write down h(t), assuming that it is causal. If you think the answer should include sinusoidal terms, your answer must reveal so.

I need explanation to this, break It down This is control theory engineering

Please Indicate your final answer in the choices! I'll rate!

Will you please help me solve questions 1 and 2?

SS Precision 3450 DELL a8ed Task #3: Remember these identities: TC = COS sin A = cos (v-s00 D -v) Convert a sine signal into a cosine signal. Let S3(t) = 5 sin(2n100t) Write s3 (t) signal in cosine form: Convert a cosine signal into a sine signal. Let S4(t) = 10 cos(2n50t) Write s,(t) signal in sine form: 直 0 F1 F2 F4 F5

Please answer in typing format solution please only Please answer in typing Ply i will be like it please thanks

I need the answer as soon as possible

Hello. I could get the transfer function from continous time, Is discrete time the same? I'm not positive how to do this one.  THank you for the help.
