I'm not whether this is the right place, but I saw geometry, n differentiation n thought, hmm, my question kinda involves both. If its in the wrong place, sorry... Anyways...Got this curve given as = theta for the sake of typing, hehe. x = a cos y = b sin I established it's a circle, because cos^2 +sin^2 =1 and subbing that in what sin and cos equal gives (x/a)^2 + (y/b)^2 = 1 Which is in the form for an equation for a circle? I'm not entirely sure on all this 2 be honest so if I'm goin wrong, feel free 2 point it out. I wanna find the tangent, the normal n the area of the circle. I've tried numerous ways but can't get the right answer.
