For what value of k is the function
f(x)= tan5x sin2x , when x is not equal to zero
k , x=0
continuous at x=0?
can we prove 4+5+5=450.
Thumbs up will be given
9. A particle moves along a path ABCD as shown in the figure. Then the magnitude of net displacement of the particle from position A to D is :
$\left(1\right)10\mathrm{m}\left(2\right)5\sqrt{2}\mathrm{m}\left(3\right)9\mathrm{m}\left(4\right)7\sqrt{2}\mathrm{m}$

19. The instantaneous velocity of a particle is equal to time derivative of its position vector and the instantaneous acceleration is equal to time derivative of its velocity vector. Therefore:
(1) the instantaneous velocity depends on the instantaneous position vector
(2) instantaneous acceleration is independent of instantaneous position vector and instantaneous velocity (3) instantaneous acceleration is independent of instantaneous position vector but depends on the instantaneous velocity
(4) instantaneous acceleration depends both on the instantaneous position vector and the instantaneous velocity.
