[ ( √ (^) √ √ )] is
equal to:
(a) (^) √ (^ ) (^) √ (b)
√ (^2) √ √ ( ) 3
(c) √ √ (^ ) (d) √ ( )( )
If x= a Ѳ, y= a Ѳ, then^ at
Ѳ=^ is:
(a) -1 (b) 1 (c) - (d)
- For | | , let y= 1+x+ +...... to ,
then^ equals to:
(a)^ (b)^
(c)
(d) x^
(^)
- If x+ y=^ , then^ is equal
to:
(a)^ (b) - (c)^ (d) -
- If y=
(^ ), then^ is equal to:
(a)^ (b) (c) sec x tan x (d)
(^ )
- If sin y= x sin (a+y), then^ is:
(a) sin (a+y) (b) (a+y) (c)^
(^) ( )
(d)^ (^ )
7. If y= (^).^ /, then
(a) 2 (b) -1 (c)^ (d)^
- If f(x)= sin (cos x), then f ‘(x) is:
(a) cos (cos x) (b) sin (- sin x) (c) – sin
(cos x)
(d) – sin x cos (cos x)
If y= (^) √√ + √√^ , then
is equal to:^

(b) (^
√^ )^
(c) (d) 0
If y= √ √ (^) √ .......,
then^ is equal to:
