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 !!
925 ÷ 8
9 ÷ 8 = 1 r1
put 1 before the 2 = 12
12 ÷ 8 = 1 r 4
4 before 5 = 45
45 ÷ 8 = 5 r 5
So it's 115 r 5
115 and 5/8 refered
