Calculate the Double Integral $$\iint _ { R } \frac { 4 + x ^ { 2 } } { 1 + y ^ { 2 } } d A , R = \{ ( x , y ) \mid 0 \leq x \leq 6,0 \leq y \leq 4 \}$$

question 122

Short Answer

Calculate the double integral. Round your answer to two decimal places.
$$\iint _ { R } \frac { 4 + x ^ { 2 } } { 1 + y ^ { 2 } } d A , R = \{ ( x , y ) \mid 0 \leq x \leq 6,0 \leq y \leq 4 \}$$

Definitions:

Nucleophilicity

A measure of a molecule or ion's strength as a nucleophile, or its ability to donate an electron pair to an electrophile.

Basicity

A measure of a substance's ability to donate electrons or accept protons, commonly applied in the context of acids and bases.

Nucleophilic

Characteristic of a chemical species that donates an electron pair to an electrophile to form a chemical bond in reaction.

t-Butoxide

A strong, non-nucleophilic base, often used in organic synthesis, derived from tertiary butanol.
