No, it's not 'gay'.That's gay
Can you please explain a bit more? I can't understand.Not quite, the angles are in AP but the actual terms may not necessarily be in AP.
Hint: Consider the identity sin(x) = cos(90-x)
Just because we have A + B + C + D + ..., doesn't always mean we have an AP.Can you please explain a bit more? I can't understand.

because you look at 6y and you need y^2 +6y +c to be a perfect square and only 9 makes it soHow did you know you had to add 9?
idk what im talking about lol this was the pattern i saw in solutionsbecause you look at 6y and you need y^2 +6y +c to be a perfect square and only 9 makes it so
so add 9 to both sides since genral equation of a circle is (x-h)^2 +(y-k)^2 = r
I'm unable to do this integral can you please help me and post your solution right now

I think this is right?Sy posted this up I think ages ago, but it's still probably the best 2U integral I've seen:
He 'completed the square'How did you know you had to add 9?
