❑ Addition, subtraction of two continuous function makes a continuous function.
Algebra of continuous function
❑ Product of two continuous functions is continuous and ratio is also continuous provided denominator is not equal to zero at the point where we are checking the continuity.
❑ Composition of two continuous functions is also a continuous function.
Polynomial functions are continuous everywhere
sinx, cosx, |x| are also continuous everywhere
log x is continuous in (0, ∞)
Points to Remember
tan x is continuous everywhere except odd multiple of π2
SOME RULES FOR DIFFERENTIATION
1. The derivative of a constant function is zero i.e.
2. The derivative of constant times a function is constant times the derivative of the function, i.e.
3. The derivative of the sum or difference of two function is the sum or difference of their derivatives, i.e.,
4. PRODUCT RULE OF DIFFERENTIATION
The derivative of the product of two functions = (first function) x (derivative of second function) + (second function) x (derivative of first function) I.e.,
6. DERIVATIVE OF A FUNCTION OF A FUNCTION (CHAIN RULE)
If y is a differentiable function of t and t is a differentiable function of x i.e.
y = f(t) and t = g(x), then
Similarly, if y = f(u) , where u = g(v) and v = h(x), then
