y=x^2*sin(x^2-x-2),-2y=x^2*sin(x^2-x-2),-2y=x^2*sin(x^2-x-2),-2用plot:forx=-2:0.001:2;y=x^2*sin(x^2-x
y=x^2*sin(x^2-x-2),-2
y=x^2*sin(x^2-x-2),-2
y=x^2*sin(x^2-x-2),-2
用plot:
for x=-2:0.001:2;
y=x^2*sin(x^2-x-2);
plot(x,y);
hold on;
end
用fplot:
clear
fplot('x^2*sin(x^2-x-2)',[-2,2])
y=(sin x + COS x)^2
y=[sin^2(x)]*[sin^2(x)]求导
y=x^2*sin(x^2-x-2),-2
求导:y=x-sin(x/2)cos(x/2).
y=2cos x (sin x+cos x)
一道三角恒等式证明题请证明sin(x+y)sin(x-y)=sin^2(x)-sin^2(y)
sin(x+y)sin(x-y)=k,求cos^2x-cos^2y
y=1-x^2 x>=0 ,y=sin|x|/x x
化简y=sin^2(x)+2sin(x)cos(x)+3cos^2(x)
y =(cos^2) x - sin (3^x),求y'
y=sin平方x+2x求y'
y =sin(2x-1)求导!
y=sin(2x+a)(0
y=|sin 2x| 周期
y=e^[(sin^2)x]求导!
y=sin(2x+a)(0
tan(x+y)tan(x-y)=sin^2x-sin^2y/cos^2x-sin^2y 顺便问一下. tan,sin,cos是什么意思?
证明sinx+siny+sinz-sin(x+y+z)=4sin((x+y)/2)sin((x+y)/2)sin((x+y)/2)
