how can i deal with math question?

I need full explanation please

Consloer the Arnhlmedlan Spiral r = sa+3.s E [0,23] plotted below in black. The tangent to the splral when a = it Is plotted In blue. A parametric fon'rl oflhls spiral can be found by using : = S as the parameter: r10} = [(3 + some), (3 +50 sham]. Find the polntaolr) = a E . The Cartesian equatlon of the tangent to the curve at not} Is 3' = B B. The Cartesian equatlon of the normal to the curve at 0(3) Is .v = a B. Note: the Maple syntax for [3, a] is [91, o] and you may nd concepts from the previous Week 9 topic useful here
