Tan (x + π/2) = [sin (x + π/2) / cos (x + π/2)] = [sin x cos π/2 + sin π/2 cos x] / [cos x cos π/2 - sin x sin π/2] = cos x / - sin x = -cot x
<span>the formula d = rt
</span><span>
r = d/t (</span>c. d over t = r<span>)
</span>t = d/r (a. d over r = t)
d = rt (<span>d. d over rt = 1)
</span><span>
so answer
</span>b. r = dt ......not equivalent to the formula d = rt
