I tried to answer them but I could not understand. please help me

\fLet m(t) = t sin(t) CYCLOID 2 and y(t) = 1 cos(t) 1.5 l 0.5 At t = 1 on I 2 3 The slope of the tangent line is C] The equation of the tangent line is y = C] (round numbers to 2 decimal places) Let x(t) = 5 . cos(t) ELLIPSE and y(t) = 3 . sin(t) 2 All answers should be decimals -2 rounded to 2 decimal places. -2 - At t = 1 ac (t) = y( t ) = dx at dy dt dy dx = tangent slope = speed\f
