How would I find static friction given the following information:
V= 45km/hr
Time to decelerate completely from 45km/hr: 3.5s
The motion of the object given is of a moving vehicle. There is a cup on the dashboard inside the vehicle that moves only when deceleration time is less than or...
nm...
Solution should be as follows:
-2xsin(x^2)
dy/du= sin(u)
du/dx= 2x
-2xsin(u) + -2xsin(U)
-2xcos(u) + -2sin(u)
= 2x(-2xcos(x^2) + -2sin(x^2))
Could someone please confirm? Thank you for the help.
Homework Equations
Take the second derivative of:
cos(x^2)
The Attempt at a Solution
cos(x^2)
dy/du = -sin(u)
du/dx = 2x
dy/dx= -2xsin(x^2)
I don't know how to begin taking the derivative of this a second time...
