NO it is not.. if its a class homework how will know its answer..

Hi Friends, I'm scratching my head for not able to figure out this problem of binary (fraction) subraction. 0.1101 - 0.00000011 = 0.11001101 Can someone please help me with steps how do i get the answer as sshown above . I tried as shown below and I am getting a different answer...

Hi friends, Please make me understand this simplest function, y = cos θ 2. in the next step it says: cos θ = sin (π/2 - θ) 3. and similarly -cos (π/2 - θ) = -sin θ. Can anyone please explain how the steps 2 & 3 are deduced. Thanks, Nesta

Thank you very much, I understand now. cos vπ cos θ + sin vπ sin θ Since sin n*pi is always zero, we can omit this. when, v=0 : cos(0π)cosθ + sin0 = cosθ v=1 : cos(1π)cosθ + 0 = -1 cosθ v=2 : cos(2π)cosθ + 0 = 1 cosθ v=3 : cos(3π)cosθ + 0 = -1 cosθ so in general we can write it as (-1)to...

Hi friends, I am not able to understand how the below shown identity becomes (-1) power v cosθ. cos(vπ − θ ) = cos vπ cos θ + sin vπ sin θ = (−1)power v cos θ ==> (-1)vcos θ Please help me understand this basic problem. Thanks, Nesta
