大佬们帮我看看吧，我以我十根头发祝各位大佬都能找到美丽漂亮的女朋友，纯纯纯小白，求助各位大佬，这个题我做的对吗，老师让用matlab解这俩题，我的t＝5

>> syms x
diff(sin(5*x^2+10)/x)

10*cos(5*x^2 + 10) - sin(5*x^2 + 10)/x^2
>> digits %10
x= input('enter data:')
y=10*cos(5*x^2 + 10) - sin(5*x^2 + 10)/x^2
fprintf('y= %f\n',y)
Digits = 32
enter data:5

>> syms x
diff(sin(5*x^2+10)/x,x,2)
ans =
(2*sin(5*x^2 + 10))/x^3 - (10*cos(5*x^2 + 10))/x - 100*x*sin(5*x^2 + 10)

>> digits %10
syms x
y=sin(x+0.5)/(x+0.5)
S=int(y,5,15)
Digits = 32
y =
sin(x + 1/2)/(x + 1/2)
S =
sinint(31/2) - sinint(11/2)
