- Homework Statement
- Find the expressions for ## dF/dy' ## when
a) ## F(y')=(1+y'^2)^{\frac{1}{4}} ##
b) ## F(y')=sin (y') ##
c) ## F(y')=exp(y') ##
- Relevant Equations
- None.
a) ## dF/dy'=\frac{1}{4}(1+y'^2)^{\frac{-3}{4}}\cdot 2y' ##
b) ## dF/dy'=cos (y') ##
I just took the derivatives above and found out these expressions, but may anyone please check/verify to see if these expressions for ## dF/dy' ## are correct? Also, I do not understand part c). What does 'exp' indicate in here?
