Finding the second derivative of the implicit function y = f (x) determined by the equation x2 + y2 = R2

The minimum value of function f (x) = x ^ 3 / 3 + x ^ 2-3x-4 on [0,2]? 5
Derivative of high school
4. The minimum value of function f (x) = x ^ 3 / 3 + x ^ 2-3x-4 on [0,2]?
5. If f (x) x ^ 3 + x ^ 2 + MX + 1 is a monotone increasing function on R, what is the range of M?

The derivative of y = cos & # 179; X / 2

y'=3cos²x/2*-sinx/2*1/2
=-3/2cos²x/2sinx/2

The n-th derivative of (SiNx) ^ 3,

Y = (SiNx) ^ 3Y '= 3 (SiNx) ^ 2cosx = (3 / 2) (1-cos2x) cosx = (3 / 2) (cosx-cos2xcosx) cos2xcosx. After the sum and difference of products, the n-order derivative of sin (AX) is calculated as follows: A ^ n * sin (ax + (n / 2) PI. The n-order derivative of COS (AX) is a ^ n * cos (AX + (n / 2) PI. Pi is pi

What is the Nth derivative of the square of SiNx

sinx(x+n pi/2)

Let y = SiNx square of E, find the second derivative, y ', y' '(0)

y=e^sinx
y'=cosxe^sinx
y''=-sinxe^sinx+cos²xe^sinx
therefore
y'(0)=1
y''(0)=1

Y = the derivative of COS ^ 2 (sin2x),

y' =2cos(sin2x) ×[cos(sin2x)]'
=2cos(sin2x)×[-sin(sin2x)]× (sin2x)'
=-sin(2sin2x)×2cos2x
=-2cos2x sin(2sin2x)
