WebJan 24, 2015 · So the sum of the integrals you're computing is zero only if c1 = c2. The fact that arcsinx + arccosx = π / 2 follows from differentiating: the function f(x) = arcsinx + arccosx has zero derivative on ( − 1, 1), so it's constant in that interval and, being continuous on [ − 1, 1] it is constant also in [ − 1, 1].

With that in mind, what is tan (pi/2)? It isn't defined. But angles that are very, very close to pi/2 do have defined tangent values, and the closer you get to pi/2, the larger and larger the values of the tangents become.
