Based on the graph, make a conjecture about whether the flow and flux of F = (-y, x) along and across Cr(t) (2 cos(t), 2 sin(t)) for = П 3πT

Find the equation to the tangent line y=8 sin x at point (π/6, 4) using form mx+b m= b= Both of them m and b equal to in decimal forms. Plz explain step by step.

Determine the constants a and b such that                                                       sin x + cos x = a sin(x + b).                                                                                Use this result to integrate   ∫ dx /( sin x + cos x) .
