Hi, I'm having a bit of trouble with my homework in some parts:
1)
Find y' if:
x^y = y^x
I have no idea on how to even start this.
As for the other:
2)
Use logarithmic differentiation:
sqrt(x)*(e^(x^2))*((x^2)+1)^10
My work:
log both sides:
log y = log(sqrt(x)*(e^(x^2))*((x^2)+1)^10
1/y * dy/dx = 1/2 * ln x + ln e^(x^2) + 10ln((x^2)+1)
Then I am confused..
Thank-you very much!
