Hello. I have difficulty solving the question int (sqrt(1-x^2)) dx using u=arcsinx. Any ideas would be greatly appreciated. all i was able to do is rewrite it as int (1-x^2)/(sqrt(1-x^2)) dx but im not too sure what to do after this.
Thanks in advance.
BTW you need to use u=arcsinx so please don't post solutions doing otherwise.
