cos(x)*(sin(x))^2*d(sin(x)),在0到90的定积分如何计算,cos(x)*(sin(x))^2*d(sin(x)),在0到90的定积分如何计算,cos(x)*(sin(x))^
cos(x)*(sin(x))^2*d(sin(x)),在0到90的定积分如何计算,
cos(x)*(sin(x))^2*d(sin(x)),在0到90的定积分如何计算,
cos(x)*(sin(x))^2*d(sin(x)),在0到90的定积分如何计算,
cos(x)*(sin(x))^2*d(sin(x))
=cos(x)^2*(sin(x))^2*d(x)
=1/4*(sin(2x))^2*d(x)
=1/8*(sin(2x))^2*d(2x)
化简到这,自己可以算了吧
(sin(x))^2=1-cos(x)^2
d(sin(x))=-d(cos(x))
代入 根据x的范围确定cosx的范围 就可以算了
分步积分法
d/dx sin^8(cos(4x))
已知tan=2,求(cos x+sin x)/(cos x-sin x)+sin^2x
化简(sin x+cos x-1)(sin x-cos x+1)/sin 2x
2cos x (sin x -cos x)+1
y=2cos x (sin x+cos x)
化简sin(x)cos(x)cos(2x)
化简sin(x)cos(x)cos(2x)
sin x cos x cos 2x 化简
(sin^2x+cos^2x )(sin^2x-cos^2x)怎么得sin^2x-cos^2x?
已知sin(x)+3cos(x)=2,求sin(x)-cos(x)/sin(x)+cos(x)=?
化简 cos^2(x)*sin^2(x)-sin^2(x)
化简 cos^(2)(x)*sin^(2)(x)-sin^(2)(x)
化简sin^4x-sin^2x+cos^2x
化简:sin^4 x-sin^2 x+cos^2 x
sin(x/2)cos(x/2)=
化简sin^4x+cos^2x
sin[cos^2(x^3+x)],求导
y=(sin x + COS x)^2
