If `f(x)=sinx` and `g(x)=e^x`, then `gof(x)` is equal to
a) `sin(e^x)`
b) `e^sinx`
c) `e^x. sinx`
d) `sinx`

If f(x)=sinx" and "g(x)=sgn sinx , then g'(1) equals

If f(x)=sinx+e^x , then f''(x)

if f(x)=e^(x) and g(x)=sinx , then the value of (f@g)(sqrt(2)) is

lim_(xoto0) x log_(e) (sinx) is equal to

If f(x)=sqrt(1-sin2x) , then f^(prime)(x) is equal to (a) -(cosx+sinx) ,for x in (pi/4,pi/2) (b) cosx+sinx ,for x in (0,pi/4) (c) -(cosx+sinx) ,for x in (0,pi/4) (d) cosx-sinx ,for x in (pi/4,pi/2)

If y=log_(e)x+sinx+e^(x)" then "(dy)/(dx) is

int(e^(x)sin x+cos x+x sin x)/(sinx)dx

If sinx+cos e cx=2, then sin^n x+cos e c^n x is equal to 2 (b) 2^n (c) 2^(n-1) (d) 2^(n-2)

"If " int sinx d(secx)=f(x)-g(x)+c, then

y=sinx+e^(x) then (d^(2)x)/(dy^(2)) is:
