$\frac { 5(x^2 y^3 z ^{1/2})^{-4} }{20(x^3 y^{-2} z^1)^5}$

$= \frac { 1 x^{-8}y^{-12}z^{-2}}{4x^{15}y^{-10}z^5}$

$= \frac {1}{4}x^{-8-15}y^{-12-(-10)}z^{-2-5}$

$= \frac {1}{4}x^{-23}y^{-2}z^{-7}$

$= \frac {1}{4x^{23}y^2z^7}$

I try to do the following integral

$\left \int_0^t v(t) = \int_0^t v_0 + v_c \{sin(\omega t + \phi) - sin(\phi)\} \right$

I end up with $x(t) = x_0 + (\frac{v_c}{\omega}) \{cos \phi - cos(\omega t + \phi)\}$

but the answer should be

$x(t) = x_0 + (\frac{v_c}{\omega}) \[\{(\frac{v_o}{v_c}) - sin \phi\} \omega t + cos \phi - cos(\omega t + \phi)\}$

So basically I have it correct but I just can't see where the term

$\{(\frac{v_o}{v_c}) - sin \phi\} \omega t$

comes from - would be extremely grateful for any help in the matter
