Question

find the equation of tangent,when the equation of the curve is parametric form​

Answer 1

Answer:

The slope of the tangent line of a parametric curve defined by parametric equations x = /(t), y = g(t) is given by dy/dx = (dy/dt)/(dx/dt). A parametric curve has a horizontal tangent wherever dy/dt = 0 and dx/dt = 0. It has a vertical tangent wherever dx/dt = 0 and dy/dt = 0.

Answer 2

A dioecious plant is one where the male and female reproductive systems occur on separate plants. While both plants produce flowers, one plant has the male reproductive parts and the other plant has the female parts. A dioecious plant requires two separate plants (a male and a female) to successfully pollinate, and only the female plant bears the fruit. Date palm is dioecious because these plants bear exclusively either male flowers or female flowers.

So the correct option is 'date palm'.
