simplify sin-1(sinx+cosx/root 2)where pie Share with your friends Share 5 123456789 answered this cud u make ur question clearer. -2 View Full Answer Athitya answered this NOTE that 1/root2 = cos45o = sin45o.and sin(A+B) = sinAcosB + cosAsinB.So sinx/root2 + cosx/root2 = sinx cos45o + cosx sin45o = sin(x+45o).So sin-1(sinx+cosx/root2) = sin-1(sin(x+45o)) = x + 45o (or) x + pi/4 24 Hariharan answered this sin x+cos x+(x-1)1/2 4 Harshsidhi Singh answered this Question no 2 8 Sanchita Srivastava answered this Here is the solution 2 Arushi answered this cos inverse {sinx + cosx/sqrt2} -9 Vignesh J answered this This is the correct anss 7 Vaibhav Shekhar answered this Easy answer 5 Subhra Kanta Mandal answered this This is the ans 1
