An easy way to show that this is not an identity is to plug in #0# for #x#.sin^-1x+cos^-1x=pi/2
The Pythagorean theorem then allows us to solve for the second leg as √1 −x2. Explanation: multiply the LHS , top and bottom by #(1+sinx)#

The three basic trigonometric functions are: Sine (sin), Cosine (cos), and Tangent (tan)..
cos( x) = cos(x) sin( x) = sin(x) tan( x) = tan(x) Double angle formulas sin(2x) = 2sinxcosx cos(2x) = (cosx)2 (sinx)2 cos(2x) = 2(cosx)2 1 cos(2x) = 1 2(sinx)2 Half angle formulas sin(1 2 x) 2 = 1 2 (1 cosx) cos(1 2 x) 2 = 1 2 (1+cosx) Sums and di erences of angles cos(A+B) = cosAcosB sinAsinB
By multiplying both numerator and denominator by #1+sinx # and using the difference of squares the result follows quickly. #cos(0)sin(0) = 0*1 = 0 != 1# In fact, if we use the identity #sin(2x) = 2sin(x)cos(x)# we can show that there are no real values for which the questioned equality is true.
