Using the chain rule.
<span><span>sin^3</span>(x) = [sin(x)<span>]^3
</span></span><span><span>d/<span>dx</span></span>[sin(x)<span>]^3</span>∗<span>d/<span>dx</span></span>[sin(x)]
</span>d/dx sinx = cosx
d/dx<span> cosx = -sinx </span>
d/dx<span> (-sinx) = -cosx </span>
d/dx <span>(-cosx) = sinx
back to where we started from!!! </span>
So,
repeat repeat repeat !!
<span>√3 * 2√2 * 5√8 * 18
2 x 5 x 18
10 x 18
180
</span>√3 x √2 x √8 =
√6 x √8 =
√48
√48 = 6 x 8 = 3 x 2 x 2 x 2 x 2 = 4√3
180 x 4√3 = 720√3
720√3 should be your answer
hope this helps
B because first you do the two triangles which =3 then you get the area for the square in the middle which is 15 then you add them up to get 18
