Suppose you want to find the difference of two sinusoidal currents, given as follows: i1(t)=I1 cos(ωt+ϕ1) and i2(t)=I2 cos(ωt+ϕ2

viktelen [127]

Answer:

120.51·cos(377t+4.80°)

Step-by-step explanation:

We can use the identity ...

sin(x) = cos(x -90°)

to transform the second waveform to ...

i₂(t) = 150cos(377t +50°)

Then ...

i(t) = i₁(t) -i₂(t) = 250cos(377t+30°) -150cos(377t+50°)

A suitable calculator finds the difference easily (see attached). It is approximately ...

i(t) = 120.51cos(377t+4.80°)

_____

The graph in the second attachment shows i(t) as calculated directly from the given sine/cosine functions (green) and using the result shown above (purple dotted). The two waveforms are identical.

Many televisions are classified by the length of the diagonal of their screens. A 60 in. television has a screen height of 32 in

Colt1911 [192]

The 60 inch is diagonal of or the hypotenuse of the TV so we are going to use a^2+b^2=c^2 and let width to be a, then we solve the problem.
a^2=c^2-b^2
oh, take the square root of both sides.
a=((c^2-b^2))^(1/2)
plug 60 for c, 32 for b, and the Width is equal to 50.75 for significant figures.
