Best ResponseYou've already chosen the best response.1this is how I calculated it. y = xCosx is the function. taking it's derivative gives the slope to be dy/dx = cosx, which when evaluated at x =pi gives 1. now equation of line is y=mx+c, we know m=1 and putting y = pi and x = pi we get c =0. thus the equation of line tangent to the curve is y =x
