sin(sin(sinx))求导

答

设u=sinx,u'=cosx
设v=sin(sinx)=sinu,v'=cosu*u'=cos(sinx)*cosx
y=sin(sin(sinx))=sinv,y'=cosv*v'=cos(sin(sinx))*cos(sinx)*cosx

What is the difference between sin30 and sin 30 degreeHi!Currently,I am studying trigonometry,and I bought a new Texas Instrument Calculator that was made in China.But When I input sin (30),it gave me an answer of -0.9880316241.That is freaking incorrect.But trickily,when I input sin (30ْ),it gave 0.5 which is a correct one.Additionally,I need to work on huge math packet everyday; so I want to get it done as fast as possible.And I at least need to pre
三角函数的数学题谁能帮我解答?1.（口答）设a是三角形的一个内角,在sin a,cos a,tan a中哪些有可能是取负值?2.已知角a的终边上有一点的坐标是P（3a,4a）,其中a不能为0,求sin a,cos a,tan a的三角函数值.请答题着写出步骤,不然我不能理解.
解答5道数学题（三角函数）1.已知 cos(π+α)=-(3/5),且α是第四象限角,则sin(α-(7/2)π)2.若f(cosx)=cos2x,则f(sin15°)的值为3.已知函数f(x)是定义在R上的偶函数,且在区间[0,+∞)上是增函数,另a=f(sin(2π/7)),b=f(cos(5π/7)),c=f(tan(5π/7)),比较a、b、c的大小关系4.若cosα=(1/5),且α是第四象限的角,则cos(-(17π/2)-α)等于多少?5.若角α的终边经过点 p(-x,-6),且cosα=-(5/13),则tanα等于多少?
