Hey jazib/princesszahra, in the partial fraction I found out A and B correctly but couldn't find C and D correctly.I knew they were wrong but proceeded with the integration anyway(didn't have time)
and of course wasn't able to get the correct answer.
How many marks out the total 10 for this question can I get considering my method was ok but calculations were wrong. And was "error carried forward" for the partial fractions integration?

u should get 5 or more!

n people who used that polar form, if u did quote the polar formula, n did xplain what does r n theta stands for, then i believe u should get full marks!
