four *(sin(two *x)^ two - cos(two *x))*exp(cos(two *x) + one) = zero
4 multiply by ( sinus of (2 multiply by x) squared minus co sinus of e of (2 multiply by x)) multiply by exponent of ( co sinus of e of (2 multiply by x) plus 1) equally 0
four multiply by ( sinus of (two multiply by x) to the power of two minus co sinus of e of (two multiply by x)) multiply by exponent of ( co sinus of e of (two multiply by x) plus one) equally zero
4*(sin(2*x)2 - cos(2*x))*exp(cos(2*x) + 1) = 0
4*sin2*x2 - cos2*x*expcos2*x + 1 = 0
4*(sin(2*x)² - cos(2*x))*exp(cos(2*x) + 1) = 0
4*(sin(2*x) to the power of 2 - cos(2*x))*exp(cos(2*x) + 1) = 0
