Hi. I'm having trouble trying to understand the relationship between inverse trig functions, especially arcsin x, and pythagorean identity. I know that because cosx=sqrt(1-(sinx)^2), derivative of arcsin x is 1/(cos(arcsin x)) = 1/(sqrt(1-(sinx)^2)arcsinx)) = 1/(sqrt(1-x^2). But how does pythagorean identity relate with antiderivative of arcsin, which is x arcsin x + sqrt(1-x^2) + C?(adsbygoogle = window.adsbygoogle || []).push({});
