(1) The phase shift of a sine function in the form `f(x)=Asin(Bx - C) + D` is `C/B` . So, to determine the phase shift of `f(x)=1/2sin(1/5x-pi)+3` , plug-in `B=1/5` and `C=pi` into the formula....

• Math
To get the phase shift and vertical shift, you must get the equation in the following form: `f(x) = acos(b(x-phi))+ c` Where a denotes the amplitude, b denotes the factor by which we divide `2pi`...

The antiderivative of a function is equivalent of the integral of that function. Therefore the antiderivative of `(x^2+2x+2)^(1/2)` with respect to `x` is equivalent to `int (x^2+2x+2)^(1/2)dx`...

• Math
The definition of `cosec(phi)` is that it is equal to `1/sin(phi)` . Therefore `cosec(2pi - theta) = 1/sin(2pi - theta)` Now, remembering the sine curve we have that `sin(2pi - theta) =...
