Code has already been provided to create the four variables a$,$ b$,$ c$,$ and d$.$ Add commands to evaluate the following expressions using these variables and assign the results to the indicated variable names:

Assign the result for to the variable Answer$1.$ Note that the values of b$,$ c$,$ and d defined in the given code are all in radians.

Assign the result for to the variable Answer$2.$ Note the absolute value of the argument to the logarithm.

Assign the result for to the variable

Answer$3.$ Note that e in this expression is the exponential function. $\%$Define variables a$,$ b$,$ c$,$ and d

a $=2\mathrm{.}2$;

b $=5\mathrm{.}1$;

c $=-3\mathrm{.}1$;

d $=1\mathrm{.}8$;

$\%$ Evaluate expressions and assign results

A$1=$ a $*$ cos$($b $*$ c $+$ d$)$;

A$2=$ d $*$ log$($abs$(($a $-$ b$)/$ c$))$;

A$3=$ a $*$ exp$($b$)*($cos$($pi $*$ c $/6+$ d$)+$ sin$($pi $*$ c $/6+$ d$))$;

$\%$ Display the results $($optional$)$
