Aboslute value of One minus Sine X is less than or equal to X. Is it sometimes, always, or never true?
Explain your answer and show work. Sometimes Example of false Sine(0)=0 1-sine(0)=1 1>0 Example of true Sine(pi)=0 1-sine(pi)=1 1<pi


I have a question on finding an expression on a sine wave could anybody point me in the right direction?
I know that the expression is y(x,t)=Asin(kx - wt + phi). The other information I have is A=0.5cm, wave length = 2cm if the phase is pi/2 when x=0 and t=0 then phi = pi/2. Now you need to find k and/or w , given the wavelength


What is the derivative of sine squared times x?
F(x)= (sin^2) x First, FYI, it is NOT sine times x; it's read sine of x! Chain rule: F

how to identify sine or cosine in modeling a sinusoid?
How will you be able to model them sine or cosine? THANKS A LOT! :D ). Looks like a hump. 2) for sine, the "s" part of the wave intersects
