Use phasors to find the value for a sum of sinusoids suppose you want to find the sum of two sinusoidal voltages, given as follows: v1(t)=v1 cos(ωt+ϕ1) and v2(t)=v2 cos(ωt+ϕ2). if you stay in the time domain, you will have to use trigonometric identities to perform the addition. but if you transform to the frequency domain, you can simply add the phasors v1 and v2 as complex numbers using your calculator. your answer will be a phasor, so you will need to inverse phasor-transform it to get the answer in the time domain. this is an example of a problem that is easier to solve in the frequency domain than in the time domain. use phasor techniques to find an expression for v(t) expressed as a single cosine function, where v(t)=[100cos(300t+45∘)+500cos(300t− 60∘)] v. enter your expression using the cosine function. round real numbers using two digits after the decimal point. any angles used should be in degrees.
