Formulas Derived from Logarithmic Function
The six basic formulas for integration involving trigonometric functions are stated in terms of appropriate pairs of functions. An integral involving and , which the simple integration formula cannot be applied, we must put the integrand entirely in terms of and or in terms of and . Notice that these formulas are reverse formulas in Differential Calculus.
The formulas derived from trigonometric function can be traced as follows:
