Today we learned about the function of trigonometric algebra in vectors, and how they applied to differentiation.

1)Find the direction angle of the vector coinciding with both the origin and the point on the function f(x) = x²+sin(x)-sin(x²)-tan(1/x)+4 where x = 6.

2)Find the norm of the vector {dy/dx sin(x²+3)-6, x²-sin(cos(x))+12}, find its direction angle, and then find its cross product of the vector and its inverse unit vector.
