f(x)=sin^2x+2sinx+3cos^2x单调递增区间
f(x)=sin^2x+2sinx+3cos^2x单调递增区间
f(x)=sin^2x+2sinx+3cos^2x单调递增区间
f(x)=2sinx+3-2in^2x =-2(sinx-1/2)^2+3.5
单调递增 sinx≤0.5 2kπ+5π/6≤x≤2kπ+11π/6
增区间[2kπ+5π/6,2kπ+11π/6]
f(x)=2sinx*sin(x+π/3) 化简
f(sin^2x)=x/sinx 求f(x)
化简f(x)=-sin^2x+sinx
f(sin^2 x)=x/sinx,为什么f(x)=arcsin√x/√x?
f(x)=sin^2x+2sinx+3cos^2x单调递增区间
已知f(x)=sinx+cosx,f'(x)=3f(x),f'(x)为f(x)的导数,则(sin^2x-3)/(cos^2+1)=?
f(x)=2sin(sinx+cosx) 求值域
f(sinx)=2sin²x-cos2x
设f(sin^2x)=x/sinx,且f∈c,求∫{[√x f(x)] / √(1-x) }dx
化简变形f(x)=[2sin(x+π/3)+sinx]cosx-√3sin^2x
函数f(x)=函数f(x)=2s函数f(x)=2sin^2x-3sinx/(2sinx+3)^2的值域为
f(x)=(1+sinx-cosx^2)/(1+sinx)奇偶性还有f(x)=x*sin(π+x)的奇偶性
判断f(x)=(1+sinx+sin^2x)/(1+sinx)奇偶性
f(x)=sinx-sin^2 x/1-sinx的奇偶性
确定函数f(x)=lg(sinx+根号1+sin^2x)的奇偶性?f(-x)=lg[-sinx+√(1+sin²x)]=lg{[-sin²+(1+sin²x)]/[sinx+√(1+sin²x)]}这步是为什么?
f(x)=lg(sinx+根号下(1+sin^2x).f(-x)=lg[-sinx+√(1+sin²x)]=lg{[-sin²+(1+sin²x)]/[sinx+√(1+sin²x)]}这步是为什么?
已知函数F(X)=2sin^2 x-sinx+3的最值
f(x)=[2sin(x+π/3)+sinx]cosx-根号3sin2x,化简
