find the value of 'a' for which the function f defined by

f(x)={a sin( pie/2) x+1 ,x < 0

{(tan x -sinx) / x^{3} ,x>0

is continuous at x=0

if Cosy= xCos(a+y), show that dy/dx= cos^{2}(a+y)/sin(a)

show that f(x) =|x-2| is continuous but not differentiable at x=2. Please reply!!URGENT!!!

if e^{x}+e^{y}=e^{x+y},prove that dy/dx= -e^{y-x}

integration of root tanx ?

if siny= xsin(a+y),then prove that dy/dx=sin^2(a+y)/sin a

differentiate wrtx

under root (1+sinx/1-sinx)
