three *(six *sin(x)^ two *DiracDelta(three *cos(x) - one) - cos(x)*sign(three *cos(x) - one)) = zero
3 multiply by (6 multiply by sinus of (x) squared multiply by DiracDelta(3 multiply by co sinus of e of (x) minus 1) minus co sinus of e of (x) multiply by sign(3 multiply by co sinus of e of (x) minus 1)) equally 0
three multiply by (six multiply by sinus of (x) to the power of two multiply by DiracDelta(three multiply by co sinus of e of (x) minus one) minus co sinus of e of (x) multiply by sign(three multiply by co sinus of e of (x) minus one)) equally zero
