 Dec14 asked The kernel of the dense set Dec13 asked The orthogonal operator onto $ran(T)$ Dec12 asked Integrate $\int_0^\pi e^{-ik\cos\theta}\sin^2{\theta} \, \mathrm{d}\theta$ Dec11 asked The dimension of the operator if the domain has dimension 2 Dec11 asked Lebesgue integrable discontinuity points Dec11 comment $\int_0^\pi g(\theta)\sin(\theta)\cos^n(\theta)\equiv 0$ imply $g(\theta)=0$? sorry for modification again Dec11 revised $\int_0^\pi g(\theta)\sin(\theta)\cos^n(\theta)\equiv 0$ imply $g(\theta)=0$? added 11 characters in body Dec11 comment $\int_0^\pi g(\theta)\sin(\theta)\cos^n(\theta)\equiv 0$ imply $g(\theta)=0$? can u write more explicitly, I don't understand Dec11 comment $\int_0^\pi g(\theta)\sin(\theta)\cos^n(\theta)\equiv 0$ imply $g(\theta)=0$? it is $(cos(\theta))^n$ Dec11 comment $\int_0^\pi g(\theta)\sin(\theta)\cos^n(\theta)\equiv 0$ imply $g(\theta)=0$? Edited. Please relook it Dec11 revised $\int_0^\pi g(\theta)\sin(\theta)\cos^n(\theta)\equiv 0$ imply $g(\theta)=0$? added 29 characters in body Dec11 asked $\int_0^\pi g(\theta)\sin(\theta)\cos^n(\theta)\equiv 0$ imply $g(\theta)=0$?
