WebThere are infinitely many solutions for the noted equation. You can calculate the first solution using a calculator. It'll probably give $5\pi/6$ (you got it wrong there with the $2\pi/3$).Then you get one set of solutions $\{5\pi/6+2k\pi k\in\mathbb N\}$. WebYou have sinθ = cosθ = sin(2π −θ). As sinθ is increasing in this range, this gives θ = 2π −θ,θ = 4π You can use the fact that ... Your angle θ is between (1,2) and the x -axis; for the dot product formula to be valid it needs to be the angle between (1,2) and ∇f = (5,10) = 5(1,2), which is of course zero and cos 0 = 1 ...
