WebCos (A + B) = Cos A cos B – Sin A sin B. Let’s equate B to A, i.e A = B. And then, the first of these formulae becomes: Cos (t + t) = Cos t cos t – Sin t sin t. so that Cos 2t = Cos2t – … WebCalculus. Graph r=2cos (theta) r = 2cos (θ) r = 2 cos ( θ) Using the formula r = acos(θ) r = a cos ( θ) or r = asin(θ) r = a sin ( θ), graph the circle. r = 2cos(θ) r = 2 cos ( θ)
