解析 x=tcos t, y=tsin t; t=π t=π , t=π , and t=π . When t=π, (x,y)=(-π ,0) and (x,y)=(-π ,0), so an equation of the tangent to the curve at the point corresponding to t=π is y-0=π [x-(-π )], or y=π x+π ^2....
If the slope of the tangent to a curve y = f(x) at a point a is f'(a) (derivative of f(x) at point (a). Then, equation of tangent in point-slope form is (y – f(a))/(x – a) = f'(a), and using equation mT× mN = −1, Equation of normal is (y – f(...
