On the trig unit circle, the axis OAx defines the trig function cos x. The 2 arcs (AM = x) and (AM'= - x) have a common projection (On) on the cos axis. Therefor cos x = cos (-x) The angle <AOM is the …

See below. (e^(x-y)cosy+cosx+2e^(2x-y))dx + (sinx-e^(x-y)siny+3y^2e^-y)dy We know that e^y ne 0 so we can simplify the former equation to obtain (e^x cosy+e^y cosx+2e^(2x))dx + (e^y sinx-e^x …
