2.2.49 Derivatives and Differentials

Condition: calculate derivatives \ (y_ {x}^{\ prime} \) the following functions: 1) \ (5 \ sqrt [5] {x^{6}}+3 \ tan x-2 \) 2) \ (y = \ frac {4-5 x} \) 3) \ (( y = \ cos ^{3} \ left (\ frac {x} {3} \ right) \) 4) \ (y = x \ cdot \ sin y-4 \) 5) \ (\ left \ {\ begin {arry} x = \ ln (t+1) \\ y = \ sqrt {(t+1)^{3}} \ end {array} \ right.
