The intelligent combination alarm uses breakthrough technology to offer a fast respnse to real fires, including smoldering and fast-flaming, as well as protect you and your family from carbon monoxide.... and Asin wt + Bcos wt = a sin (wt + a) given that 'a' is an angle with a point P (A, B) on its terminal side. Example 1 Transform y = 3 sin 2t + 4 cos 2t to the form y = a sin ( w t + a ). Also find period, amplitude, frequency and phase shift.

**Identifying wave-number sign after FFT2 MATLAB Answers**

If y =Asin(wt), then dy/dt=-Awcos(wt). I know why the sin becomes minus cos, but why does the w come out of the sin bracket to become a part of the main equation? Can someone solve this equation and take me through the procedure? Thanks....

For a transverse wave on a string the string displacement is described by y(x,t)=f(x-at), where f is a given function and a is a positive constant. how to keep pancakes warm in a crock pot eg. f(x) = A sin (kx) 2 For a wave travelling in the +x direction, the displacement y is given by y (x,t) = f (x - vt) f(x) = y(x,0) = A sin(kx) For sinusoidal waves, the shape is a sine function, eg., Then y (x,t) = f(x – vt) = A sin[k(x – vt)] or y (x,t) = A sin (kx – ωt) with ω = kv A -A y x (A and k are constants) Sine Waves y = A sin (kx – ωt) = A sin [ constant – ωt] ω
