If y= cos x^(@), then (dy)/(dx) is?

If y=a sin x + b cos x , then ((dy)/dx)^2+y^2 is

If y=a+b x^2,\ a ,\ b arbitrary constants, then find dy/dx

If y=(sin(x+9))/(cosx) , then (dy)/(dx) at x = 0 is: a. cos9 b. sin9 c. 0 d. 1

If y=cos^(-1)(cosx) ,then (dy)/(dx) at x= (5pi)/4 is equal to (a)1 (b)-1 (c)0 (d)4

If y=asinx+bcosx , then y^2+((dy)/(dx))^2 is a (a)function of x (b) function of y (c)function of x and y (d) constant
