_ ^ dx 1 - x = - Vidyadip

MCQ

$\int_{}^{} {\frac{{dx}}{{1 - \sin x}}} = $

A
$x + \cos x + c$
B
$1 + \sin x + c$
C
$\sec x - \tan x + c$
✓
$\sec x + \tan x + c$

✓

Answer

Correct option: D.

$\sec x + \tan x + c$

d
(d) $\int_{}^{} {\frac{{dx}}{{1 - \sin x}} = \int_{}^{} {\frac{{(1 + \sin x)}}{{1 - {{\sin }^2}x}}\,dx} } $

$ = \int_{}^{} {{{\sec }^2}x\,dx + \int_{}^{} {\tan x\,.\,\sec x\,dx} } $$ = \tan x + \sec x + c$.

Ravi and Rashmi are each holding $2$ red cards and $2$ black cards (all four red and all four black cards are identical). Ravi picks a card at random from Rashmi and then Rashmi picks a card to random from Ravi. This process is repeated a second time. Let $p$ be the probability that both have all $4$ cards of the same colour. Then, $p$ satisfies
