I am having trouble with the definition of indefinite orthogonal group. On Wikipedia, it says it is the Lie group of all linear transformations of an n-dimensional real vector space that leave invariant a nondegenerate, symmetric bilinear form of signature (p, q), where n = p + q. However, this d...

Evaluating $\int_0^{\pi/2} \log(a^2\cos^2 x+b^2\sin^2 x) dx$ using the concept of differentiation under integral sign. My Attempt: Given $$\int_0^{\pi/2} \log (a^2 \cos^2 x+b^2 \sin^2 x) dx$$ Here, $a$ and $b$ are parameters. Considering $b$ as a constant $$F(a)=\int_0^{\pi/2} \log(a^2 \cos...
I have removed the tag real - I suppose it was created by mistake: math.stackexchange.com/posts/3611377/revisions
Queries which show also editors who added/removed the tag: data.stackexchange.com/math/query/1105163/… data.stackexchange.com/math/query/1038474/…
The above queries return more than 40 past occurrences of real - so it seems that this is a common mistake.
