The problem is given as a piece-wise function f(t)={1, 0≤t<4; 0, 4≤t<5; 1, t≥5}. I am asked to write the function in terms of unit step functions and then find the Laplace Transform of the function. I can do the Laplace if I could ever get the unit step function. ...
Using the Heaviside unit step function, determine a formula forthe hourly cost of running the air conditioner at t hours, assuming it is turned on when t = 0 andleft on permanently. What is the hourly cost at the 80 minute mark?
The Laplace transform of a unit step function can be calculated using the formula F(s) = ∫0∞ e-stf(t) dt, where f(t) is the unit step function. This integral can be evaluated using integration by parts, and the final result is 1/s.Post...

In CDS view, quantity will be fetched from database table & then it will check if the Unit of measure in which quantity needs to be displayed on UI is different from unit of measure stored in database table, then it will get the conversion formula maintained (in MARM) using associations...
Now use the formula. Recall that tan 30° = sin 30° / cos 30° = (1/2) / (√3/2) = 1/√3, as claimed. See how easy it is? How do I find cosecant with the unit circle? To determine the cosecant of θ on the unit circle: From the center of the circle draw the ...
