Integrating Derivatives of Trig Functions
Indeed, using the fantastic qualities of the 6 trigonometric functions, we can generate various kinds of beautiful integrals.
The 6 integrals above are just using the derivatives of the 6 trigonometric functions. Notice that only the integrals of and are here, leaving the other four trigonometric functions. Then what about their integrals? How many of all the 6 trigonometric functions have indefinite integrals that are compositions of the basic functions we covered already (e.g. logarithmic, exponential, absolute value, polynomial, factorial, trigonometric etc.)?
