two *sin(x)^ two *DiracDelta(cos(x) - one) - cos(x)*sign(cos(x) - one) = zero
2 multiply by sinus of (x) squared multiply by DiracDelta( co sinus of e of (x) minus 1) minus co sinus of e of (x) multiply by sign( co sinus of e of (x) minus 1) equally 0
two multiply by sinus of (x) to the power of two multiply by DiracDelta( co sinus of e of (x) minus one) minus co sinus of e of (x) multiply by sign( co sinus of e of (x) minus one) equally zero
