The Newton df(x) is used for derivative by:
Caunchy
Lagrange
Newton
Leibniz

Derivative of y = (x + 1)(?x + 1) is:
None of these
dy/dx = (?x+1) (1)
dy/dx =(x+1)(1/2x)
dy/dx = (x +1) 1/2?x +(?x +1)

If f(x)=2x2+1 then f'(-1)=
4
-4
2
-2

If y=af(x) then dy/dx =
f'(x)af(x) lna
None of these
f'(x)af(x)
f'(x)af(x)/ lna

y=in(f(x)) then dy/dx=
f'(x)/f(x)
f(x)
f'(x)/ lna
1/ f(x)

If y = Sinx then.
none of these
y2 = y
Y2 =y1
y2 = y
