Question

If y = -3 csc (3-7x^2), find dy/dx.

Answer #1

Find the solution of the following differential
equation:
(?^3 y/dx^3)-7(d^2 y/dx^2)+10(dy/dx)=e^2x sinx

Find dy/dx if y= (x^3+5x)(4x^2+10)^9

find dx/dx and dz/dy
z^3 y^4 - x^2 cos(2y-4z)=4z

Find dy/dx by implicit differentiation:
A.). x^4 + y^3 = 3
B.). 5x^2 +3xy - y^2 =7
C.) x^3(x+y) = y^2(4x-y)

Find dy dx/dy implicit differentiation. (x + y^2)10 = 9x^2 +
2

(X^2 y+y^3)dx-x^3 dy=0

a. *If
y=x3+7/x^2/3
, then find dy/dx . Make sure your answer is
fully simplified.
b. *If y=5x-84x+3 , then
find dy/dx .
c. *If
x=(x2-5x+3)(2x2+4)
, then find f ‘(x).
Please neatly show your work.

Solve the given differential equation
y-x(dy/dx)=3-2x2(dy/dx)

Find the derivatives dy/dx and d^2y/dx^2, and evaluate them at t
= 2.
x=t^2 ,y = t ln t

Solve: 1.dy/dx=(e^(y-x)).secy.(1+x^2),y(0)=0.
2.dy/dx=(1-x-y)/(x+y),y(0)=2 .
