three *(two *tan(two *x)^ two + two)*sin(log(tan(two *x)))^ two *cos(log(tan(two *x)))/tan(two *x) = zero
3 multiply by (2 multiply by tangent of (2 multiply by x) squared plus 2) multiply by sinus of ( logarithm of ( tangent of (2 multiply by x))) squared multiply by co sinus of e of ( logarithm of ( tangent of (2 multiply by x))) divide by tangent of (2 multiply by x) equally 0
three multiply by (two multiply by tangent of (two multiply by x) to the power of two plus two) multiply by sinus of ( logarithm of ( tangent of (two multiply by x))) to the power of two multiply by co sinus of e of ( logarithm of ( tangent of (two multiply by x))) divide by tangent of (two multiply by x) equally zero
