SOLVED: x(t)Consider the signal above, which is the triangular pulse function x(t) = A ()a) Working directly from the integral definition, find the Fourier transform of x(t). Youranswer should be in terms of sinc function. Note: you'll probably need to do integration by parts, or go to a table of integrals, to solve this one. Also, you may need the identity sin2 x = 2 [1 - cos 2x] . (b) Using the tables of Fourier transform pairs, and in particular the differentiation property. to solve for X(w)

A symmetrical triangular pulse of maximum height 0.4 m and total length 1.0 m is moving in the positive x direction on a string on which the wave speed is 24 m / sec. At t=0 the pulse is entirely located between x=0 and x=1 m. Draw a graph of the transverse velocity versus time at x=x2= 1 m. | Numerade

The triangular voltage pulse shown in Fig. P6. 16 is applied to a 500 μF capacitor. a) Write the expressions that describe a(t) in the five time intervals t20 s. b) Derive the expressions for the capacitor current, power, and energy for the time intervals in part (a). Use the passive sign convention. c) Identify the time intervals between 0 and 20 s when power is being delivered by the capacitor. Repeat for the time intervals when power is being absorbed by the capacitor. Figure P6.16 | Numerad

Drink this when you’re stressed! The adrenal glands are small, triangular-shaped glands located on top of each kidney and produce essential hormones like cortisol, adrenaline, and aldosterone. These hormones help regulate various essential functions throughout the body, including metabolism, immune response, blood pressure, stress response, and electrolyte balance. When we’re stressed our adrenals work overtime to compensate, which can result in feelings of fatigue, increased cravings, poor slee
