Answer:
5 * 10^10
Step-by-step explanation:
that's it bro. learn how to do it. then you won't need brainly anymore foo'.
It's hard to type and hard to read the "inverse tangent" function, as you've seen (above).
So, use "arctan x" instead.
Then the problem becomes: "differentiate cos (arctan x)."
You must apply first the rule for differentiating the cosine function, and next apply the rule for differentiating the arctan function:
(d/dx) cos (arctan x) = - sin (arctan x) * [1/(1+x^2)]
PQ is bisected by RS at R. It means that PRQ is a line segment with PR = RQ and each of half of PQ.
RQ = PQ/2 = 1/2 [ 4 3/4 ] = 1/2 * 19/4 = <em>19/8 </em> = 2 3/4
