[karush]

232.q1.4a sketch the region of integration

$\displaystyle\int_{-2}^{2}\int_{\sqrt{4y^2}}^{4-y^2}
f(x,y)\,dx \,dy$

this is what i did with desmos don't know how
to shade the integrated area

Re: s4.13.t.71 angles of triangle PQR

sorry your correct
but there was a typo in the OP
it should of been
$\displaystyle\int_{-2}^{2}\int_{\sqrt{4-y^2}}^{4-y^2}
f(x,y)\,dx \,dy$

minus sign missing

how did you fill with red ... paint??
