The discussion focuses on integrating the expression $\sin(u) + u^6$. The initial confusion arose from misplacing parentheses, leading to the incorrect interpretation of the function as $\sin(u + u^6}$. Clarification was provided that the correct expression is simply $\sin(u) + u^6$, which simplifies the integration process. The participant expressed gratitude after understanding the correct approach. Proper placement of parentheses is crucial for accurate mathematical interpretation and integration.

Make the substitution $t = \sin x$.

I understand now
Hello!
I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem.
Given:
##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0##
##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1##
##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0##
I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
