The question -
R is the region inside the circle
My attempt (converting to polar) -
Assuming we can find a quarter of the circle, than multiply by 4 for the total area...
Here I'm stuck and quite frankly it's looking a lot more complicated than I imagine it should, can someone please point out the error in my working?
On the off chance I am correct so far, can I treat those sections as radians? I don't believe I can as that wasn't the context they were used originally, so what would I do?
Thanks for your time folks.
Obviously it's a big confidence boost to know I'm getting something right, it's been a hell of a night
In regards to the however, isn't it used in the context of a distance (the radius) rather than radian's for the sin and cos?
So wouldn't and only be correct if it was in fact radians, which from my understanding it is not? For some reason I'm thinking it should be something like
I'm sure I'm wrong, but it's always important to find out why your wrong, rather than simply getting the right answer
