Homework Statement
Find the equation of plane which contains the line [itex]l:\left\{\begin{array}{l} x=t+2 \\y=2t-1\\z=3t+3 \end{array}\right.[/itex], and makes the angle of [itex]\frac{2\pi}{3}[/itex] with the plane [itex]\pi:x+3y-z+8=0[/itex].
The Attempt at a Solution
My attempt was to find the normal vector of plane which contains the line by the cross product of vector [itex]\vec{a}[/itex] of line and some vector created between points [itex]P(2,-1,3)[/itex] of line and point [itex]Q(x,y,z)[/itex], than by using the formula to find angles, but this leads me to complications.
I think there's another way to solve this, which I don't know.
Thank you
