four *x*cos(x) - (x^ two + three)*sin(x) + two *sin(x) = zero
4 multiply by x multiply by co sinus of e of (x) minus (x squared plus 3) multiply by sinus of (x) plus 2 multiply by sinus of (x) equally 0
four multiply by x multiply by co sinus of e of (x) minus (x to the power of two plus three) multiply by sinus of (x) plus two multiply by sinus of (x) equally zero
4*x*cos(x) - (x2 + 3)*sin(x) + 2*sin(x) = 0
4*x*cosx - x2 + 3*sinx + 2*sinx = 0
4*x*cos(x) - (x² + 3)*sin(x) + 2*sin(x) = 0
4*x*cos(x) - (x to the power of 2 + 3)*sin(x) + 2*sin(x) = 0
