Assume a and b are constants
4x+y=b
y=b-4x
gradient(m)=-4
y=ax³
dy/dx=3ax²
since line is tangent to curve,
3ax²=-4

a=-4/75

(x+2)平方 + (y+1)平方=13的圆心为(-2,-1),所以过圆心和(0,2)的直线斜率为:[2-(-1)]/(0-(-2))=3/2,所以切线方程显然与过圆心和(0,2)的直线斜率互为负倒数:所以为:-1/(3/2)=-2/3,已知斜率和过(0,2)点的条件,可得:y=(-2/3)x+2,整理得:2x+3y=6

1.An equation of the line tangent to the graph of y=cos(2x) at x= π/4 is
A.y-1= -(x-π/4)
B,y-1= -2(x-π/4)
C.y=2(x-π/4)
D.y= -(x-π/4)
E.y= -2(x=π/4)
【Solution】:
dy/dx = -[sin(2x)](2) = -2sin(2x)
dy/dx|(x=π/4) = -2sin(π/2) = -2
Let tangent line be y = -2x + c
Sub x=π/4 and y = cos(π/2) = 0 sub into y = -2x + c,we get c = π/2
So,tangent line is y = -2x + π/2
Ans :None of the above
(typo happened with your ans)
2.d/dx cos^2(x^3)=d[cos²x³]/dx = -2(cosx³)(sinx³)(3x²) = -3x²sin²(2x³)
3.0.5∫e^0.5 dt= 0.5(e^0.5)t + c (maybe mistyping)

4.the graph of y=3x^4-16x^3+24x^2+48 is concave down for
A.x0
C.x< -2 or x> -2/3
D.x2
【Solution】:
y = 3x⁴- 16x³ + 24x² + 48
dy/dx = 12x³ - 48x² + 48x = 12x(x² - 4x + 4) = 12x(x - 2)²
Let dy/dx = 0
We have x₁= 0;x₂= 2
d²y/dx² = 36x² - 96x + 48 = 12(3x² - 8x + 4) = 12(x-2)(3x-2)

两边求导
12x+3y+3xy'+4yy'+17y'=0
y'=-(12x+3y)/(3x+4y+17)
则过点(-1,0)的切线斜率为
k=-[12*(-1)+3*0]/[3*(-1)+4*0+17]
=12/14
=6/7
所以切线方程为y=(6/7)(x+1)
即6x-7y+6=0
垂线的斜率为k'=-1/k=-7/6
方程为y=-7/6(x+1)
即7x+6y+7=0

题目的意思应该是指,求出k的值,使得y=2x+k,是曲线y=6x²+4x的切线.
直线y=2x+k的斜率为2
对曲线求导可得:y'=12x+4
所以y'=2,得:2=12x+4 x=-1/6
代入曲线可得:y=1/6-4/6=-1/2
即点(-1/6,-1/2)为切点.
此点应该在直线y=2x+k上
代入即可求得:k=-1/6

若是y=-6x=1则y=1,x=-1/6这是一个点无法平行.

x^2+x=-6x+b
