True or Flase

A stationary point is also called a ________ if it is either a maximum or a minimum point? dy/dx = dy/du ? du/dx is known as ________ rule? The derivative of sin x w? r? t? cos x is ________? When y = f(x), y is called the independent variable? The notation f¢(x) for derivative of y = f(x) was introduced by Newton? For finding the derivatives of trigonometric functions f(x), x must be in degrees?

When f ¢(x) < 0 for each x e ] a,b [ then f(x) is increasing? Relative maxima is not necessarily the highest point of the graph? f¢¢(x) is positive at the point x = c where f has relative maxima? The increment in x should always be positive? A function f(x) has a minimum value at x = a if? If y = f(x) then dy/dx is? The derivative of Sin x0 w? r? t? to x? Two numbers such that their difference is 50 and product is minimum are?
