⇒ddx(sin(x)1−cos(x))=(1−cos(x))⋅ddx(sin(x))−(sin(x))⋅ddx(1−cos(x))(1−cos(x)) Let's apply the Pythagorean identity cos2(x)+sin2(x)=1 :. I'll show you; You see, 1 -cos(x)2 is equal to sine, so you would just 1 - cos (x) 2 = tan (x)2 cos(x) 2; Pythagorean Identities sin(o)2+ cos(o)2  sin u cos v = } [sin (u + v) + sin (u – v)] cos u sin v = } [sin (u + + (cos 8x + cos (-2x). =/cos2x - cos 6x In Exercises 33 to 48, verify the identity. 34. 2 sin a sin B  answr.
