As below

Explanation:

Standard form for sine function is

$y = A sin (B x - C) + D$ $y = A sin (Bx - C) + D$

Given : $y = - 0.4 sin (10 x + \frac{π}{2})$ $y = -0.4 sin (10x + pi/2)$

Amplitude $= | A | = 0.4$ $= |A| = 0.4$

Period $= \frac{2 π}{| B |} = \frac{2 π}{10} = \frac{π}{5}$ $= (2pi)/|B| = (2pi)/10 = pi/5$

Phase Shift $= \frac{- C}{B} = \frac{- (\frac{π}{2})}{10} = \frac{- π}{20}$ $= (-C)/B = (-(pi/2))/10 = (-pi)/20$ , $\frac{π}{20}$ $pi/(20)$ to the left

Vertical Shift $= D = 0$ $= D = 0$
