Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `integer`

This variable doesn't seem to be used anywhere.

Advice

(a) and (b):

$\int_\var{d-2}^\var{d}\simplify[all]{{a}*x-sin({b}*x)}\,dx=\left[\simplify{{a}*x^2/2+cos({b}*x)/{b}}\right]_\var{d-2}^\var{d}=\var{a1}$

$\int_\var{d}^\var{d+3}\simplify[all]{{c}/x^{a+1}+{b}*sqrt(x)}\,dx=\left[\simplify{{-c/a}/x^{a}+{2*b/3}*x^(3/2)}\right]_\var{d}^\var{d+3}=\var{a2}$

(e) and (f):

$\int_{-2}^\var{a-2}\simplify[all]{{c+1}*exp(x/{b})-{a}}\,dx=\left[\simplify{{b*(c+1)}*exp(x/{b})-{a}*x}\right]_{-2}^\var{a-2}=\var{a3}$

(g) and (h):

$\int_\var{b}^\var{b+a}\simplify[all]{{c}/({b}*x)+{b}/{a+1}*cos({c}*x)}\,dx=\left[\simplify{{c}/{b}*ln(x)+{b}/{c*(a+1)}*sin({c}*x)}\right]_\var{b}^\var{b+a}=\var{a4}$

(i) and (j):

$\int_\var{a}^\var{a+1}\simplify[all]{x^{b-1}/{b+2}-{d}+{c}*exp({-a}*x)}\,dx=\left[\simplify{x^{b}/{b*(b+2)}-{d}*x-{c/a}*exp({-a}*x)}\right]_\var{a}^\var{a+1}=\var{a5}$
