# i need help with calculus!!!

• how do i get the derivative prime and secondary on this equation:

[arccsc 1/2(x)(3xsecx +9x^3tan)^1/5]^1/4 + x^3pi/4+4x] / 2x^2sin(x^3+ 1/2lnxcos(x^2))

find the optimization, and find local max and min and see if there is a global max is can be proven.
this is so hard my teacher is a bad teacher!!!!
