The linear approximation of f(r)= sin r near 0 is y = r, so we writesinr=x+E(r).Since sin r is differentiable at r = 0, Theorem 3.6 tells us thatlim_(x→0)(E(x))/x=0 If we take = 1/10, then the definition of limt guarantees that there is a 6 0 such that|(E(x...

Question: Find a formula for the graph in terms of f(x)=sinx or g(x)=cosx.NOTE: Enter your answer in terms of sinx or cosx.y=◻ There are 3 steps to solve this one.
Find the values between 0 and 4π where the tangent line to the graph of y=sin(x)cos(x) is horizontal. Tangent Line: Lines that are parallel to the x−axis or the tangent lines, horizontal to the graph of the curve, have slope = 0 or...
解析 切线是垂直的?不是水平切线对函数求导y=cosx/(2+sinx)y‘=[-sinx(2+sinx)-(cosx)^2]/(2+sinx)^2=-(2sinx+1)/(2+sinx)^2可知y’=0的点的切线是水平的所以2sinx=-1x=7π/6或11π/6所以点(7π/6,1/3)(11π/6,-1/3)出的切线是水平的...
SOLUTION The tangent line is horizontal when the derivative is equal to zero. To get the derivative of sin2x, we use the Product Rule. d/(dx)sin^2x=d/(dx)(sinxsinx)=sinxcosx+sinxcosx The product of sin x and cos x is equal to zero when either sin x or cos x is equal to ...
and y = cos(π/2) = 0 sub into y = -2x + c, we get c = π/2So, tangent line is y = -2x + π/2Ans : None of the above(typo happened with your ans)2.d/dx cos2(x3)=d[cos²x³]/dx = -2(cosx³)(sinx³)(3x²) = -3x²sin²(2x³)3.0.5∫e0.5 ...
